摘要：

Forced commutated cycloconverters (PWM cycloconverters) have no energy storage components except for small ac filters for the elimination of switching ripples. Therefore, the PWM cycloconverters can be made compact and highly reliable compared with the conventional converter-inverter systems. The PWM cycloconverters, however, directly connected the input terminals to the output terminals by the switching devices. As a result, if the input source voltages are asymmetrical and/or contain harmonics, the influence of the distortions directly appear on the output terminals. This problem is a major obstacle to using PWM cycloconverters instead of the conventional converter-inverter systems. This paper presents a novel control method for PWM cycloconverters. By using this control method, sinusoidal input and output current waveforms and unity input displacement factor can be obtained. Moreover, the compensation of the asymmetrical and/or harmonic contaminated input source voltages is easily realized.
