Active Adjustable Coil Receiver for Adaptive Output Power Based on
Wireless Power Transfer
Abstract
Wireless charging systems typically operate under variable load
conditions and the power required by different loads in space varies.
The power required by different loads is different in the space. At
different stages of charging, the characteristics of the load may also
change. WPT needs to adjust the voltage and power in real time to meet
the needs of different voltages and different working conditions. The
power transfer power of WPT can be optimized for variable loads. This
paper introduces an active adjustable coil receiver with adaptive output
power. The active adjustment of the output power is achieved by changing
the different positions of the sliding rod in the receiving coil. This
design allows the receiver power to remain stable in the range of 3-21
W. Receiver can meet the different power requirements of the load, and
is not sensitive to factors such as transmission distance and offset.
The system can reduce the complexity of charging and power supply system
design, effectively promote the application of wireless power
transmission in the field of multi-load equipment.
