Abstract
From the careful analysis of the transformed dq system equations of a PWM Voltage Source Converter ( PWM - VSC ), a novel voltage control is proposed which is based on the derivative of in-phase current component of line currents and the relation between dc-link voltage and in-phase current component. A simple logical algorithm to implement the proposed scheme is also presented at transient state. The sinusoidal PWM is adopted at steady state. The simulation results show good transient characteristics.
