Abstract

The error-tracking mode (ETM) is a novel constantly sampled pulsewidth modulation (PWM) scheme for a voltage-source power conversion system (PCS) interconnecting with a utility network to regulate its AC current waveform. It guarantees, theoretically, the AC actual current to be settled within an arbitrary target allowable error. Generated current harmonics can be restricted by a relatively small filter. Both the minimum on- and off-duration times of switching commands are assured by the PWM scheme itself. A four-quadrant 1-kVA PCS in which gate commands are produced by the novel PWM scheme has been successfully experimented upon for the first time, and it has justified the ETM-PWM theory. This paper describes the design procedure and experimental results of the trial setup
