A Novel Contactless Power Supply Device Based on Electromagnetic Induction

Aiming to the disadvantage that the security of traditional power supply is difficult to guarantee in some special environments, this paper proposes a novel contactless power supply device (CPSD) based on electromagnetic induction. The circuit structure of the device is simulated and analyzed, and a full-bridge inverter circuit and a rectifier circuit are adopted in the main circuit. Also, the pulse-width modulation (PWM) is used to control the circuit with a series-series compensation circuit. The PWM waveform required for the controllability is obtained by realizing the voltage control of load terminal. Finally, the CPSD is simulated by an MATLAB software, and the good performance of the device is verified.
