Abstract

The soft-switching buck inverter, which is mainly applied to solve the contradictions between the switching frequency and the shoot-through problem along with the dead-time effect, is proposed in this paper. A detailed analysis of the relationship between the range of the duty ratio to realize soft-switching as well as the additional voltage stress and the current stress is conducted. In addition, a 1 kW prototype is designed and established. Results of simulations and experiments verify the validity of the theoretical analysis. Furthermore, the proposed soft-switching buck inverter has a strong practical significance in situations where medium and high power outputs are required.
