A Study of 'Pump Type' Matrix Converter with High Voltage Transfer Ratio

摘要

Matrix converter is a direct power converter that can convert energy from an AC source to an AC load without the need of the bulky and limited-lifetime storage elements in the dc link. While this topology has many advantages, its voltage transfer ratio is limited to 0.866.This paper deals with a three-phase 'pump type' matrix converter with an innovative topology.The theoretical analysis of the high-performance power converter is discussed. Furthermore, the simulation results are also presented in order to verify the result of theoretical analysis.All simulations have been carried out in PSIM.
