    Abstract

    An increased attention has been detected to develop smaller and lighter high voltage power converters in the range of 50V to 400V domain. The main applications for these converters are mainly focused for Power over Ethernet (PoE), LED
    lighting and AC adapters. This work will discuss a study of using enhancement mode gallium nitride switches to form a 50V quasi-square-wave zero-voltage-switching buck converter running at 2-6 MHz under full load. The designed
    converter achieved 83% efficiency converting 50V input voltage to 12.2V at 9W load.
