A novel and simple current controller for three-phase PWM power inverters

A new feedback current controller for three-phase pulsewidth modulation (PWM) power inverters is presented. To achieve robustness, fast dynamical response, reduced switching frequency, and simple hardware implementation, an improved three-level hysteresis sliding-mode controller is used. All voltage...

Description
Summary:A new feedback current controller for three-phase pulsewidth modulation (PWM) power inverters is presented. To achieve robustness, fast dynamical response, reduced switching frequency, and simple hardware implementation, an improved three-level hysteresis sliding-mode controller is used. All voltage vectors are accurately selected in order to minimize the current error.
