摘要

Single phase hysteresis current controllers have traditionally been implemented using two level modulation which is known to be inferior to three level modulation. This paper presents a simple, low cost, and effective technique to allow single phase hysteresis current regulation to be implemented as three level modulation process. This achieves a substantial reduction in the magnitude and variation of the switching frequency, thus improving efficiency, while retaining all of the advantages identified with hysteresis current control. The operation and control of the inverter are described, together with simulation and experimental results.
