Abstract

This paper describes a microprocessor-based digital control system for three-phase voltage source inverters (VSIs) with second-order LC filter for high- and variable-frequency applications. In order to economize computing time and for dynamic reasons, the innermost capacitor current control loop is realized as a simple but efficient hysteresis controller. An outer state controller-based on a continuous or discretized mathematical model-ensures sinusoidal load voltage and current
