Abstract

This paper presents a dual-bridge inverter approach to eliminate the motor common mode voltage and resulting bearing and leakage currents. The novel dual-bridge inverter is controlled to generate balanced excitation of the induction motor under PWM inverter operation. Theoretical analysis, simulation results and experimental results are presented to verify this concept
