Abstract
This paper proposes two kinds of novel switching method for a single phase current-controlled voltage-type ac-to-dc converter. Proposed are modifications of the conventional hysteresis current control, and are named by the half suppressing method and unipolar method, respectively. The first one suppresses an inactive half of the four switching signals and uses active another half for current control. The second method uses only one, a quarter of switching signals suppresed the others. Both the simulation and experimental results show that proposed methods are more efficient in switch utilization and have comparable or better performance when compared with conventional method.
