Abstract
This paper introduces a new non-isolated high gain dc-dc topology with magnetic coupling and voltage multiplier technique (VM). The high voltage conversion ratio can be achieved by selecting the suitable turn's relation of the magnetic coupling. The VM circuit has been utilized for further extending the voltage rate. Also, the voltage spike through the switch can be clamped by VM circuit which leads the decrease the peak voltage through the switch. Moreover, there is only single switch, so the control circuit will be simple and a switch with lower conducting resistance can be selected. For validating the proficiency of the proposed structure, technical analysis and simulation results with 200W power level and 25 KHz operating frequency is provided. Furthermore, the comparison survey with other topologies are prepared for demonstrating the effectiveness of the recommended converter.
