Dual-bridge inverters: A new approach to bearing currents and conducted EMI. Final report
Technical Report
·
OSTI ID:354812
The purpose of this research report is to present a dual-bridge inverter approach to eliminating the motor common-mode voltage and resulting bearing and leakage currents and conducted electromagnetic interference (EMI). The report reviews first the existing technologies in solving the problems concerning the application of adjustable speed drives. The theoretical analysis is then given for the operation of the novel dual-bridge inverter which is controlled to generate balanced excitation of the induction motor under pulse-width modulation (PWM) operation mode. Finally, simulation and experimental results are presented to verify this concept.
