Saturable reactor assisted soft-switching technique in PWM DC-DC converters

A family of saturable-reactor-assisted soft switching pulse-width-modulated (PWM) DC-DC power converters is presented. It uses saturable reactors to achieve efficient soft switching in a wide load range, from no-load to full-load, with no substantial increase in conduction losses. An approximate analysis and key experimental results are presented. In addition, a summary of voltage conversion ratios and voltage and current stresses for this family of converters is provided.<<ETX>>
