【Abstract】 Matrix converter (MC) has the low volume,the sinusoidal input current,the bidirectional power flow,and the lack of the bulky and limited-lifetime electrolytic capacitors,so it’s the ideal choice to realize integration of motor and frequency converter.In this paper matrix converter motor system (MCMS) and several important technologies,such as MC,the design of the input filter circuit and the clamp circuit of MCMS,safety commutation and modulations are analyzed. Simulation shows the feasibility of this way.更多还原
