A. Von Jouanne et Hr. Zhang, A dual-bridge inverter approach to eliminating common-mode voltages and bearing and leakage currents, IEEE POW E, 14(1), 1999, pp. 43-48
This paper presents a dual-bridge inverter approach to eliminate the motor
common-mode voltage and resulting bearing and leakage currents. The novel d
ual-bridge inverter is controlled to generate balanced excitation of the in
duction motor under pulsewidth modulation (PWM) inverter operation, Theoret
ical analysis, simulation results, and experimental results are presented t
o verify this concept.
