Wireless charging system is divided into transmitter and receiver, through electromagnetic induction, wireless charging board and mobile phone through the space magnetic field, to transmit electricity. The design of the wireless charging board, the circuit design of the loss of each contact, directly affect the efficiency of wireless charging.
1. Component loss affects the speed of wireless charging.
The internal resistance of components is small, and the conversion efficiency of the system is high. The use of small internal resistance transistor and other components, can greatly enhance the efficiency of wireless charging. But the low resistance, the cost will be relatively high.
2. Transmitter end and receiver can not match timely, resulting in loss, affecting the speed of wireless charging.
The power output of the transmitter will be flexibly adjusted according to the receiver, and too much power loss will be generated when the transmission power is matched with the receiving end. Optimize the two parts of the timely matching, can improve the efficiency of wireless charging.
3. Electromagnetic coil advantages and disadvantages of wireless charging efficiency to promote a significant relationship
The use of electromagnetic coils in the field of wireless charging also has an effect on the efficiency of wireless charging in the whole system. Wireless charging coils and low loss coils are required on both the transmitter and receiver terminals to greatly enhance the efficiency of wireless charging.
