A Research on the Wireless Power Transmission Performance of a Strong Resonant Electric Vehicle with Series-parallel Resonance

Abstract

Analysis of WPT system drive scheme, the paper expounds series resonance inductance and series resistance of parallel resonant working mechanism, design combination of series and parallel resonant switch drive mode and string - type and combination type electric circuit. According to the different kinds of compensation of the leakage inductance of the transformer to form various harmonic compensation induction wireless power transmission topology, it is concluded that the strong resonant design, topology of voltage, current and other characteristics are given.
