This paper deals with the stand alone solar PV (Photo Voltaic) supplied PMSM (Permanent Magnet Synchronous Motor) drive for water pumping system. An interlink Boost converter is used between solar PV panel and DC bus of PMSM drive. The DC bus voltage of PMSM drive is maintained constant by controlling the duty cycle of boost converter. Three phase VSI (Voltage Source Inverter) is controlled to supply...
This paper presents an improved power quality bidirectional voltage source converter (VSC) fed permanent magnet brushless DC motor (PMBLDCM) drive. The single-phase bidirectional VSC is a pulse width-modulated (PWM) rectifier. It ensures unity power factor operation at supply terminals under wide speed variations of PMBLDCM with minimum total harmonic distortion (THD) of AC supply current. A three-phase...
