Inga converter: a new single-switch flyback-current-fed topology

A novel DC-DC converter is presented, whose significant advantages are the single power switch, single input inductor, purely capacitive output filter, isolation and operation at constant frequency in a conventional pulse width modulation scheme. The new converter is suitable to operate over a very wide input voltage range and can be employed in power factor correction and multiple output power supply. Theoretical analysis and experimental results were taken from the converter rated at 300 W/50 kHz.
