Novel zero-current-switching-zero-voltage-switching converters

A new family of zero-current-switching-zero-voltage-switching (ZCSZVS) pulse-width-modulation (PWM) converters are proposed. With the proposed ZCSZVS concept, the PSPICE simulation results of the application to a single-switch three-phase PFC rectifier have been obtained and compared with those of hard-switching and ZCT applications in order to show the excellent performance of the proposed ZCSZVS concept.
