Harmonic Suppression Strategy for Grid-side Current in Single-phase Matrix Converter Based Wireless Power Transfer System
摘要
Abstract
Aimed at the problem of large harmonic content of grid-side current in a single-phase matrix converter based wireless power transfer(MC-WPT)system,a harmonic suppression modulation strategy is proposed to effectively reduce the low-order harmonic content and total harmonic distortion(THD)of grid-side current.The voltage and current characteristics of resonant tank are analyzed,the equivalent circuits at two fundamental frequencies are obtained based on the parameter normalization method,and the mathematical model of MC-WPT system is derived accordingly.On this basis,with an objective of eliminating the low-order harmonic content,the optimal modulation wave of the H-bridge on the receiving side is obtained by using the calculation method,so that the low-frequency component of grid-side current only contains the line frequency component,thereby reducing the THD of grid-side current.Finally,an experimental platform was built to verify the feasibility and effectiveness of the proposed harmonic suppression modulation strategy.关键词
