Analysis and design of fully DCM clamped-current boost power-factor corrector with universal-input-voltage range

This paper proposed a fully discontinuous-conduction-mode (DCM) clamped-current boost power-factor-corrector (CCB PFC). The reverse-recovery of the boost diode is eliminated so that the overall efficiency is improved. Low THD and high PF input current waveforms are still achieved. It is attractive i...

Description
Summary:This paper proposed a fully discontinuous-conduction-mode (DCM) clamped-current boost power-factor-corrector (CCB PFC). The reverse-recovery of the boost diode is eliminated so that the overall efficiency is improved. Low THD and high PF input current waveforms are still achieved. It is attractive in cost-sensitive medium to low power level applications. Detailed analysis is presented, and a 100 W prototype with universal-input-voltage-range has been designed to verify the theoretic analysis.
