Abstract :
This paper presents an ac-dc-ac switched-mode power supply composed of two power stages. The first stage is an interleaved boost-flyback converter, and the second one is a ZCZVT full-bridge McMurray inverter. The analytical study of both structures is described, and some results are presented in order to validate the proposal.
