The efficiency of this circuit is very low, because there is only half a wave peak high frequency so the loss is relatively large, but the principle is quite simple and easy to produce.
3, the so-called wireless charging technology only uses the electromagnetic wave induction principle, and the related AC induction technology, in the transmission and connectionThe receiver uses the corresponding coil to send and receive inductive AC signals for charging. Nothing high-tech, just magnetic fields! The charger has a coil, the battery has a coil, and when you put it close, it forms something like a transformer. But it's very inefficient, and it's very radioactive.
4, principle: the DC-DC switching power supply is divided into two parts at the high-frequency transformer, using resonant coupling; Then use RFID technology for data communication and current feedback. In a single-phase bridge rectifier circuit, if a filter capacitor is connected, the output voltage (that is, the voltage at both ends of the capacitor) is open when the load is openIs the peak of the AC input voltage, that is: U output =414*U input, that is, the root of 2 times the input voltage.

2, but the load, the general design is 2 times the U input. The larger the filter capacitance, the higher the output voltage, and the lower the vice versa. In a single-phase bridge rectifier circuit, if there is no filter capacitor, the output voltage is 0.9 times of the AC input voltage when the load is open, that is, U output =0.9*U input. Under load, the formula remains the same: U output =0.9*U input. This conclusion is applicable to both bridge and full wave rectifier circuits.
3, mobile phone wireless charging is a relatively novel charging method, the principle is actually very simple, that is, the ordinary transformer primary and secondary separate to achieve the purpose of wirelessYes. Of course, the working level of wireless charging is relatively high, and even the role of energy transfer can be achieved between the iron core and the direct coil can be abandoned. Drawings to there are a lot, but will not send pictures, to tell you about the simplest wireless charging.

Electromagnetic induction wireless charging, when the current of the power supply through the coil (wireless charger's power supply coil) will generate a magnetic field, other unenergized coil (mobile phone side of the powerProximity to the magnetic field generates an electric current that charges the phone. As shown below.
The principle of electric field coupled wireless charging is to transmit electrical energy through the induced electric field generated by the coupling of two sets of asymmetric dipoles in the vertical direction. Suitable for short distance charging, high conversion efficiency, the position can not be fixed; However, the disadvantage is that the equipment is large and the power is small. Therefore, at present, among the four wireless charging methods, electromagnetic induction wireless charging scheme is the most mature and most widely used in business.
Principle of electromagnetic induction wireless charging This wireless charging method is relatively popular in the current market, and can realize the original wireless chargingIt all depends on the efficient conversion of magnetic and electrical energy. In the charging process, the wireless charging device can directly generate magnetic flux through induction magnets at both ends, and then it can use the linear change of magnetic flux to generate the required electricity, and finally, the device successfully collects electric energy for charging the mobile phone.
Radio wave This is a more mature technology, similar to the early use of ore radios, mainly composed of microwave transmitters and microwave receivers, can capture the radio wave energy bounced from the wall, while adjusting with the load while maintaining a stable DC voltage. This way only one installation on the wallA transmitter with a plug, and a "mosquito" receiver that can be installed in any low-voltage product.
