【Abstract】 Multi-levels power conversion is a new technology which can meet the demand of high voltage conversion with high power and make the multi-levels converter to be able to realize the power conversion using low voltage devices. The matrix-converter is a new AC/AC inverter, it is of the merits of small volume, ideal output and input waveform, high power factor, rapid dynamic response and bi-directional power transmission. The authors combine these two techniques to form a new topology, i.e.multi-levels matrix converter. The simulation and experiment results demonstrated the feasibility and reliability of new converter and its control strategy. It is shown that this topology is available.This work is supported by National Natural Science Fund of China (No.50007007).更多还原
