Abstract

In this paper, we have proposed a Parallel Resonant Soft Switching Inverter based on Delta-Modulation Method. The conventional full-bridge inverter generates switching losses due to the hard switching. The proposed inverter operates soft switching using a DC-link switch and resonant circuit. So, all of the switches in the proposed inverter operates soft switching. Therefore the proposed inverter can reduce not only switching loss but also capacity and size of passive devices due to the resonant elements. The validity of the proposed inverter is verified thorough the theoretical analysis and simulation.
