| One way to increase the voltage gain and reduce the voltage stress on the switch is by utilizing coupled inductors. However, a major drawback of this technique is the occurrence of voltage spikes on the switch, which are caused by the discharge of energy from the leakage inductance. This paper proposes a zero current switching step-up converter to mitigate the voltage stress on the switch resulting from the high voltage gain of the converter. This enables the utilization of switches with lower drain-source resistance, leading to a more affordable price. The converter's auxiliary circuit requires minimal elements and does not require an additional switch, resulting in a straightforward control circuit. Another advantage of the converter is the transfer of energy from the auxiliary circuit to the output. Various operation modes of the proposed step-up converter have been investigated, and the converter's behavior has been simulated using PSpice software. To validate the accuracy of the analysis and simulation results, an 80W prototype has been implemented. | ||
