Bridgeless Hybrid Converter Fed Switched Reluctance Motor For Household Appliances

A non-isolated hybrid bridgeless (NHB) converter is designed for power quality management in switched reluctance motor (SRM) drive. A low cost SRM motor drive is selected for household appliances and is fed through NHB converter for efficient motor control. This converter is operated in discontinuous current mode (DCM). A mid-point is developed using zeta and canonical switching cell (CSC) converter. NHB converter is developed to compensate for grid voltage variations ranging from 90V to 270V. Split capacitor voltages are regulated for speed control of SRM drive. NHB converter components are selected to perform satisfactorily for 600 W power rating. This study presents an analysis, design, and simulation of a low-cost SRM drive with a front-end converter aimed at household appliances.
