Closed Loop Topology of Converter for Variable Speed PMSM Drive

  Devang B Parmar

The discontinuous mode operation (DCM) of all single-switch topologies is most suitable for low power applications, somewhere these converters there outstanding characteristics of power factor correction using a very simple control scheme with only one voltage feedback loop. The Permanent Magnet Synchronous Motor is used to construct low power rating application such as Refrigerator, Washing Machine, House-hold appliances, Medical Equipment, Wide speed range of servo drives and industrial robots. CCM fly back converter sustains the same voltage stress as, but less current stress than its DCM counterpart, when delivering the same output power. As for output voltage performance, both CCM and DCM fly back converters perform equally well in terms of output voltage regulation. In the light of efficiency, the CCM fly back converter is superior to its DCM complement, which suffers from the larger conduction and switching losses.

Keywords- Power Quality, Total Harmonic Distortion. Topology of Fly back AC-DC Converter, High Frequency Isolation, Permanent Magnet Synchronous Motor.
