| Abstract: | In this paper a novel ZVS isolated Boost converter is presented. This converter is employed the LCD snubbers and coupled winding in boost inductance, the switches can realize zero voltage turn off and the surge voltage of switch is low. The converter features simple transformer structure, low input current ripple and high efficiency. It is very suit for low-to-high voltage conversion circuit. The principle of this converter is analyzed in details. Simulation and experimental results in that the novel converter is feasible. |
