In this paper, a half-bridge LCC high voltage converter with integrated magnetics is proposed. The resonant tank is formed with high conversion ratio transformer in one core, resulting in cost effectiveness. Using IGBT, operation in below resonant frequency with hybrid soft start method are suggeste...
