Abstract
This paper presents a power supply system with pre-regulator using zero voltage switching (ZVS) interleaving two-transistor forward converter for high input voltage and high power application. A SMPS has a advantage that a good efficiency, small size and light weight but has a noise problem. A linear power supply system has a advantage that a good stability, low ripple and noise but has a disadvantage that a big size, low efficiency and heat problem. To alleviate these problems, we propose an power supply system using dual ZVS interleaving two-transistor forward pre-regulator. The proposed converter is verified on a 1kW, 50kHz experimental prototype.
