Soft-switching Z-source inverters with coupled inductor

This paper presents a new resonant soft-switching quasi-Z-source inverter. On the basis of the quasi-Z-source inverter, the proposed inverter inherits the features of high voltage boost ability, circuit simplicity and high reliability. A resonant network with coupled inductor is employed to achieve the soft-switching scheme. All active devices (switches and diodes) in the inverter are tuned on and off under zero voltage or zero-current switching condition. The principle of the proposed converter and analysis of operation are proposed. Simulation and experimental results are given to illustrate the soft-switching characteristics. The theoretical analysis and simulation agrees well with experimental results.
