Abstract |
|
A bidirectional isolated full bridge converter with conversion ratio around nine times, soft start up, soft switching and which is equipped with a fly back snubber and passive capacitor diode snubber have wide applications in battery charging/discharging circuits. Voltage spikes caused by current difference between leakage inductance and current fed inductor currents, the current spikes due to diode reverse recovery, and the current and voltage stresses can be reduced. It can achieve near ZVS and ZCS soft-switching features. In this paper operation principle of proposed converter with 48V on low side and 360V on high side is described and analysis is presented. Simulation of circuit with 48V at low voltage side and 360V at high voltage side has been presented. |
