  • Low cost high efficiency unipolar converter for permanent magnet synchronous motors
    Horvat, Janko, 1980- ; Milanovič, Miro
    This paper describes the development of a low cost power converter for permanent magnet synchronous motors (PMSM). Only low side switches are used for motor control similar to unipolar brushless DC ... (BLDC) converters but much higher efficiency is achieved because no snubber circuit is needed. Instead of being dissipated on snubbers the energy is re-circulated over a buck converter. So the converter topology can be shown as a multi "phase" BOOST - "single" phase BUCK converter (C-dump converter) where the PMSM windings represent the inductors of the boost part. PMSM control is performed with signals derived from embedded Hall sensors and developed low cost circuitry.
