Control of three-phase switching converters: A sliding mode approach

The selection of the switching logic and the control for PWM three phase switching power converters (inverters and rectifiers) is presented. The approach is based on the deliberate introduction of the sliding mode motion in the control system. The structure of the switching matrix for PWM three phase inverters and three phase rectifiers is the same, so the same structure of the sliding mode controller can be used and the same switching strategy is obtained for both PWM inverters and rectifiers.
