In order to solve the problems of narrow output voltage regulating range
low regulating precision and efficiency in existing inductively coupled power transfer(ICPT)systems brought about mainly by using the fundamental wave of the inverter to transfer power
a new ICPT system with fundamental wave and harmonic wave two-path parallel transmission is proposed. By building the fundamental energy path and harmonic energy path after the inverter output using the high frequency and energy characteristics of the harmonic wave
the fundamental wave and harmonic wave of the inverter are extracted and used to widen the regulating range and improve the system efficiency. Firstly
this paper expounds the working mechanism of the proposed system. Secondly
the influence of the critical parameters on system efficiency and frequency selection characteristic is analyzed. Thirdly
according to the basic idea of the proposed system
a voltage regulating method with wide range is proposed. Finally
the theoretical analysis of the proposed system and the feasibility of voltage regulation method are verified by experiment.
