A New forward type zero voltage switching inverter

In this paper, a new soft-switching forward type inverter is presented for low power applications. This inverter is composed of a main and a clamp switch on the DC side and low frequency switches on the ac side. The proposed inverter is PWM controlled and soft switching condition is also achieved for the DC side switches. The unique features of the proposed converter are high efficiency, low weight and volume, and good dynamic response. The principles of circuit operation and theoretical analysis are discussed and simulation results are presented.
