A Three-phase Matrix Converter with High Voltage Transfer Ratio based on Pump-type Circuit
Abstract:
Nowadays, AC speed regulation has become an important means to realize the automation of electric drive system and energy saving. As the core of the AC adjustable speed system of AC converter technology has become one of the research direction in the field of the hottest.
Matrix converter can adjust the output frequency, phase and control the input current and output voltage, the input power factor can be adjusted, is one of the most advanced power converters. But its disadvantages are also obvious, the maximum voltage transfer ratio is only 0.866, and the converter is more complex.
This paper completes the theory research and the design of the control unit, broke through the traditional topology of matrix converter, the study and design of a pump type matrix converter, the voltage transfer ratio is adjustable, and the mechanism to solve the problem of low transmission ratio, and has obtained the ideal effect and simulation engineering environment. Finally the simulation waveform is analyzed by using the PSIM software, the correctness and effectiveness of the verification experiment.
Keywords: Matrix converter, the voltage transfer ratio of the bidirectional switch, PSIM software
