摘要:A new soft switching pulse-width-modulated (PWM) fly back dc/dc converter with a simple auxiliarycircuit for PMDC drives with ANN is proposed. This isachieved by using two very simple active auxiliarycircuitsoneactive, the other passive. The outstanding featureof the new converter is that it allows its main powerswitchesto operate with zero current switching (ZCS) and with fewer conductionlosses than conventional full-bridgeconverters.By adding this auxiliary circuit to the conventional pulse width modulation isolated fly back converter, allpower semiconductor devices are soft switched. In addition, the proposed converter frequency is constant and has noadditional current stress in the main switch in comparison with conventional ones. Simulation and experimental resultsjustify the theoretical analysis.
