Design and Implementation of a Single Switch High Gain Boost Topology: Structure, Ripple Control and ZCS

The need for high gain DC-DC converters has lately increased in tandem with the utilization of renewable energy supplies. Particularly appealing are that do not require inclusion extra power switches and/or other passive elements to system. As a result, this study proposes non-isolated single switch converter ultra-high voltage (UHG) is appropriate most conversion systems, like solar installations. With only MOSFET working within suitable duty cycle region, proposed provides significant and around 95% efficiency. Moreover, UHG turned on zero current switching (ZCS) mode, resolving diode recovery issue. recommended converter’s modes, steady-state parametric study, circuit variables stress devices, all thoroughly explained. Comparisons have been done comparable topologies presented literature, lastly, experimental results depending 200W (20V input, 320V output voltage) given validate operation design.
