Abstract :
This paper presents an AC-DC-AC switched-mode power supply composed of two power stages. The first stage is a new topology of two-switch forward converter, and the second one is a new topology of three-level half-bridge inverter. The forward structure presents soft switching and also symmetrical output voltages to supply the half-bridge inverter. The analytical study of the converters is described, and some results are presented in order to validate the proposal.
