Current Control of VSI-PWM Inverters
... A load consisting of a stalled induction motor was simulated to observe the operating characteristics of the hysteresis controller when the load counter EMF is zero. The line current and current reference are shown in Fig. 9. The inverter has periods of high switching frequency which are interrupted ...
