Abstract :
This paper proposes chopper-cycloconverters with simplest topologies, minimum devices and simple control modes for energy saving in motor systems. Typical waveforms and control regulations are presented. Passive freewheeling unit is introduced for reduce active device and simplifying the control method. Theoretical and simulation analyses show the significance in auxiliary small size applications for higher power factor operation than that of the traditional cycloconverters. The total power consumptions of them should be emphasized adequately in today´s lacking of energy.
