Abstract :
Connected with drawbacks of the traditional AC-DC-AC inverters, the operation principles and the running characteristics of dual-PWM inverter are presented. In order to improve the DC bus voltage stability and the system reliability, the integrated direct power control strategy with power feedback is proposed, and the virtual-flux based direct power control schemes are introduced into the dual-PWM inverter to improve the dynamic response speed and anti-jamming ability. The simulation results verify the validity of the proposed schemes.
