3-phase AC/DC boost converter power factor control via traditional and second order sliding modes

A full bridge boost power converter is considered in order to convert 3-phase AC into DC voltage with power factor correction. Desired current trajectories are generated so that, if they are followed, the output voltage will have the desired value and the converter will have a unity power factor. Traditional as well as two types of second order (super-twisting sliding and prescribed convergence law algorithms) sliding mode controllers are used to control the converter. The controlled converters is simulated and studied for the effectiveness of the proposed control algorithms.
