Abstract

In this paper, A voltage source PWM converter which achieves bidirectional power flow between a $3{\phi}$ AC supply and a DC bus voltage is described. And the paper considers both the steady state and transient response of such a device, and develops mathematical models to describe its performance under the digital control system. As a result the AC line current becomes sinusoidal and the input power factor is improved to unity.
