Abstract
© 2003 IEEE.A new control method for single-phase full- bridge PWM inverters is proposed in this paper. The proposed controller has a capability to realize a zero steady- state output voltage error with fast response. The zero steady-state output voltage error is achieved by using a controller that is derived by using the virtual LC resonant circuit. Fast response is obtained by using a virtual resistance that is connected in parallel with the filter capacitor. The validity of the proposed method is verified by experimental results.
