Abstract

— A power factor corrected bridgeless SEPIC converter-fed induction motor drive as a cost-effective solution for high-power applications. An approach of speed control of the induction motor by controlling the voltage of the voltage source inverter is used with a single voltage sensor. This facilitates the operation of voltage source inverter at fundamental frequency switching by using the electronic commutation of the induction motor which offers reduced switching losses. A bridgeless configuration of the SEPIC converter is proposed which offers the elimination of the diode bridge rectifier, thus reducing the conduction losses associated with it. A power factor corrected bridgeless SEPIC converter is designed to operate in discontinuous inductor current mode to provide an inherent power factor corrected at AC mains. The performance of the proposed drive is evaluated over a wide range of speed control and varying supply voltages with improved power quality at AC mains. The operation of the PFC BL SEPIC converter is classified into two parts which include the operation during the positive and negative half cycles of supply voltage.

Key Words

Bridgeless (BL) SEPIC converter discontinuous inductor current mode (DICM), power factor corrected (PFC), power quality.
