High voltage gain non-isolated DC-DC converter with two-coupled-inductor is presented in this paper. Based on single switch quadratic boost topology, by incorporating coupled-inductor cell into pre-stage boost cell and stacking the output voltage, the proposed converter can achieve high voltage gain...
A compact quasi-Z-source DC/DC converter is presented with high voltage gain, isolated output, and improved efficiency. The improvements in size and performance were achieved by using a square wave inverter with only two output switches driving an isolating transformer in push-pull mode, followed...
