| Abstract: | This paper introdues a kind of capacity feed back storage battery constant current discharging device based on three-phase PWM converter, and modeling of three-phase PWM VSC using complex transfer functions in synchronous rotating frame is introduced. Design and analysis of current controller for PWM VSC is presented using the complex vector notation model. Based on the power balance concept, mathematic model of discharging current is set up, and the control scheme is suggested. Lastly experimental results validate the performance of the device. |
