How is the intelligent wireless charger scheme developed 2022-04-11 09:37:47
The intelligent wireless charger scheme has the functions of automatic induction charging and intelligent power-off after full charging. It is not only suitable for electronic products with various charging voltages and capacities, but also can charge multiple different electronic products at the same time. The work adopts the design idea of intelligent wireless charging, which has the advantages of convenient use and wide application, and has high promotion and application value. Then, let's learn how to develop the scheme of intelligent wireless charger! Introduction to intelligent wireless charger scheme With the rapid development of electronic technology, the number of global mobile phone users has reached 3.3 billion. With MP3, MP4 and other peripheral electronic products, less than two people have mobile phone electronic products that need to be charged on average. At present, cable connection charging is widely used. The cable interface of this charging mode will usually have poor contact and other phenomena after long-term use. Moreover, a charger is not widely applicable, and different chargers need to be used according to the types of electronic products. It is very troublesome to find a suitable interface and wiring when charging. Charging all kinds of portable electronic products is an annoying trouble. In order to improve the above phenomenon, it is necessary to develop intelligent wireless charger. Working principle of intelligent charger The intelligent charger uses the principle of electromagnetic induction. In the non-contact charging system, it uses wireless transmission mode to charge, rather than wire (charging line) to transmit power. There is no physical interface for charging. Compared with general chargers, it avoids the trouble of inserting wires and pulling out batteries, and has the working principle of general chargers; The work adopts the design idea of one (charger) to many (inductive load) charging and intelligent charging; After the wireless charger charges the load, the indicator light will change from green light to seven color light, and the mobile phone can correctly display the charging state to intelligently complete the charging process. The experimental product is mobile phone. Advantages of Smart Wireless charger scheme: 1) Low cost The circuit is composed of a pulse generation unit, a power amplification unit, a filter unit, a comparison unit and a transmitting and receiving unit. Each unit is composed of several small components, which is simple to make. 2) One to many charging One charger can charge multiple loads. Each household can use one charger for the whole family. With the increase of load, the work efficiency will be improved, which can not only save electricity but also reduce unnecessary costs. 3) Convenient Compared with ordinary chargers, it not only reduces the trouble of plugging in and out, but also avoids the phenomena of inappropriate connector and poor contact. The elderly can also use it easily. 4) Intellectualization The intelligent wireless charger scheme can automatically conduct inductive charging as long as the inductive load is placed on the charger. Through information feedback, after the inductive load is fully charged, it can automatically turn off the power supply to realize the intelligence of the charging process. The smart wireless charger scheme will greatly improve our life. With the popularity of wireless charging technology, people can charge all devices with one charger. Moreover, with the popularization of this technology, wireless charging transmitters can be easily found in all places where we live, live and work. Charging transmitters can also be installed in cars, planes, hotels and offices. This means that people can charge their appliances anytime, anywhere without carrying wires. The above is how to develop the intelligent wireless charger scheme. If you need more information, please feel free to contact us!
Scheme of electromagnetic induction intelligent wireless charger 2022-03-25 08:57:03
With the rapid development of electronic technology, the number of people using smart phones in the world is increasing. By 2017, 69% of the world's people will use smart phones. At present, cable connected charging is widely used. The cable interface of this charging method will have poor contact for a long time. Moreover, a charger is not widely applicable. Different chargers need to be used according to the types of electronic products. It is very troublesome to find appropriate interfaces and wiring when charging. The charging of various portable electronic products is a headache. In order to improve the above phenomena, we need to develop a smart wireless charger scheme. Now let's learn about the electromagnetic induction Smart Wireless charger scheme!   The wireless charger scheme uses the principle of electromagnetic induction. After 1N4148 rectification and filtering, the voltage U1 is compared with the reference source uo. During charging, the current of the transmitting coil increases with the increase of inductive load. The load voltage of 0.33 Ω is amplified by 23 times through the operational amplifier, the green light is on, and there is no inductive load after 10 seconds, so it will shut down automatically; Press the reset button, U1 is much brighter than uo colorful light, indicating that it is charging; When no-load or full charge, U1 is less than uo, and the charger will restart. The specific circuit analysis is as follows 1) When switch S2 is disconnected, the charger is in intelligent charging as a whole. The colorful lamp flashes and UI reaches a high level. At this time, Q5 is saturated, and the voltage uceq is 0.67v, which is lower than the sum of the on voltage of Q2 and Q4 (1.34v). Q2 and Q4 constitute Darlington and cut off at the same time. After the charger is started, relay K1 is closed and K2 becomes closed at the same time. When there is inductive load, Q3 is cut off at this time, and capacitors C5 and R9 form an RC charging circuit. When the capacitor charging voltage reaches the on voltage of Q2 and Q4, Q2 is turned on to saturate Q4. When relay K1 is fully charged by the adsorbed inductive load or there is no inductive load, the green light is on, that is, UI is low level. Click the reset switch and the charger will restart. When the inductive load is fully charged (or no inductive load), the capacitor C5 is charged. At this time, after the relay is powered off, the relay K2 is closed. At this time, C5 and R13 form an RC discharge circuit to give C5 rapid discharge. Its voltage is ut. 2) During S2 shutdown, the whole charging circuit is in the process of manually cutting off the power supply. The wireless charger has the functions of automatic induction charging and intelligent power-off after full charging. It can also charge a variety of different electronic products at the same time. It is not only suitable for electronic products with various charging voltages and capacities. The wireless charger scheme summarizes the following advantages. 1) Low cost The circuit is composed of a pulse generation unit, a power amplification unit, a filter unit, a comparison unit and a transmitting and receiving unit. Each unit is composed of several small components, which is simple to make. 2) One to many charging One charger can charge multiple loads. Each household can use one charger for the whole family. With the increase of load, the work efficiency will be improved, which can not only save electricity but also reduce unnecessary costs. 3) Convenient Compared with ordinary chargers, it not only reduces the trouble of plugging in and out, but also avoids the phenomena of inappropriate connector and poor contact. The elderly can also use it easily. 4) Intellectualization As long as the inductive load is placed on the charger to realize the intellectualization of the charging process, it can automatically inductive charging. Through information feedback, after the inductive load is fully charged, it can automatically turn off the power supply. The above is the scheme of electromagnetic induction intelligent wireless charger. If you need more information, you can contact us at any time!  
Circuit analysis of wireless charger 2022-03-10 09:07:45
Wireless charging has entered reality from dream and turned from concept to commodity. In recent years, it has led a new trend in mobile phones, electric vehicles and other fields. It proves that wireless charging technology has a very broad market prospect. The following is a micro distance wireless charger circuit scheme. This scheme is a feasibility exploration experiment. Then, let's learn about the circuit analysis of the wireless charger scheme! Scheme and principle of wireless charger The wireless charger scheme converts DC into high-frequency AC, and realizes the wireless power supply through the mutual inductive coupling between the primary and secondary coils without wired connection. The basic scheme is shown in the figure. The wireless charger is composed of power transmitting circuit, power receiving circuit and charging control circuit. Power transmission department The power supply of the transmitting unit of the wireless charger scheme includes 220V AC and 24V DC, which are selected by the relay J. According to the principle of AC priority, the normally closed contact of relay J in the figure is connected with DC (battery BT1). Usually S3 is on. When AC power is supplied, the rectified and smoothed DC adsorption relay J of about 26V acts in the form of AC power supply, the DC power supply BT1 is disconnected from the power transmission circuit, and LED1 (green) emits light to indicate its state. The 24V DC power selected by the relay J is mainly supplied to the transmitting coil L1. In addition, it is supplied to the integrated circuit IC2 after being depressurized by IC1 (78l12). Therefore, in order not to make the action of J affect the stable action of the transmitting circuit, the capacitance of capacitor C3 must be more than 2200uf The wireless transmission of power is actually realized through the mutual inductance of transmitting coil L1 and receiving coil L2, in which L1 and L2 constitute the primary and secondary coils of coreless transformer. In order to ensure sufficient power and as high efficiency as possible, it is appropriate to select a high modulation frequency and consider the high-frequency characteristics of the equipment. Generally, the distance between the receiving coil L2 and the transmitting coil L1 is only a few centimeters, which is close to coaxial, so high transmission efficiency can be obtained. The principle of charging control circuit unit is shown in Figure 2-3. The effective value of 1.6mhz sine wave voltage induced by L2 is about 16V (no-load). After bridge rectification (composed of four 1N4148 high-frequency switching diodes) and C5 filtering, about 20V DC is obtained. As the power supply of the charging control unit. As the prototype of the feasibility exploration experiment, the wireless charger scheme is only for small capacity lithium-ion batteries and lithium polymer batteries of about 100mah. It is suitable for pocket digital products such as MP3, MP4 and Bluetooth headset. There are no obstacles in principle to popularize it into high-capacity batteries. Of course, from laboratory prototypes to market products, there may be long and arduous work such as electromagnetic radiation leakage, cost control and product technology, market entry and consumption start. The above is the circuit analysis of the wireless charger scheme. For more information, please feel free to contact us!
