High Voltage Gain Zero-ripple Non-isolated Converters With a Coupled-inductor
摘要
Abstract
High voltage gain non-isolated DC-DC converters with low input current ripple have attracted much attention for photovoltaic cells, fuel cells and other renewable energy system applications. A zero input current ripple high voltage gain non-isolated converter was proposed, which combines a zero input current ripple boost converter and a coupled-inductor cell to achieve high voltage step-up. In addition, diode reverse recovery losses of the proposed converter was alleviated due to the leakage inductance of the transformer, but it cause serious voltage spike stress of the switch. Therefore, the passive lossless clamp circuit was adopted to recycle the leakage energy and thus a low-voltage-rated MOSFET with lowRds_on for reduction of the conduction loss and cost can be chosen. In addition, the proposed converter can nearly achieve zero input current ripple, and remove the electromagnetic interference (EMI) filter without sacrificing the performance of the converter. Consequently, small passive components, light weight and low costs can be achieved. Steady state analysis of the converter and operating characteristics was developed. Finally, experimental results from a 100W 40V/200V prototype were presented to verify the analysis of the proposed converter.关键词
