Abstract :
A new non-isolated step-up converter with high voltage gain is proposed on this work. It is suitable for applications with a high voltage gain between the input and the output. In this converter, the output to input voltage ratio, for a given duty cycle, can be raised adding transformer turns ratio. Another important feature of this converter is the lower blocking voltage across the controlled switches compared to similar circuits, which allows the utilization of switches with low on-resistance RDS(on) MOSFETs. In order to verify the feasibility of this topology; principle of operation, theoretical analysis, and experimental waveforms are shown for a 1 kW laboratory prototype
