Abstract :
This paper proposes a family of single-phase single-stage step-up/down ZVS inverters derived from adding an LC series resonant circuit to the conventional differential inverters and controlling them in such a way that ZVS happens for individual switches. Differential inverters are single-stage step-up/down inverters. Applying the ZVS technique to them enables them to operate under a higher switching frequency. This results in the smaller reactive components. Smaller reactive components results in lower losses, lower volume and faster dynamics. In this paper, optimization using MATLAB to minimize the auxiliary current is done for three types of differential inverters: buck, boost and buck-boost inverters. Simulation with PSIM is carried out and experimental results are provided to verify the theory.
