Abstract

This paper presents a family of constant-switching-frequency pulse-width-modulated controllers for single-phase power-factor-correction (PFC) circuits that operate at continuous-conduction mode (CCM). Both trailing- and leading-edge pulse-width modulation (PWM) are used. These controllers do not require the multiplier and rectified-line-voltage sensor, which are needed by traditional control methods, and they can be implemented with a unified control circuit. Controller examples are analyzed and verified experimentally
