Abstract :
In many applications such as photovoltaic (PV) farms, high-reliability step-up DC-DC converters have gained increasing attention. One of the issues with the power converter is the reliability problem. The high-step converters with lower-power semiconductors are more reliable. This article introduces a novel step-up DC-DC converter with zero current switching (ZCS) for semiconductor equipment. The suggested converter has only one switch and therefore is more reliable. The performance of the traditional converter and the suggested one has been investigated in the MATLAB/Simulink environment. The simulation results show that the suggested converter has a higher gain than the traditional one and when employed in a PV system, it injects more power into the network, indicating its superiority. At the same time, under similar variations in radiation and to reach the maximum power point, the suggested converter's duty cycle changes less, which shows its more suitable performance.
