Abstract

A new feedback current controller for three-phase IGBT PWM inverters is presented. The method is based on a current loop with two nonlinear three-level hysteresis controllers. The voltage vectors applied to the load are accurately selected in order to minimise the output current error. The controller structure, based on simple analog-digital hardware implementation, is shown and experimental results are presented
