Abstract
A circuit for use in a switched mode power supply includes a dual-boost power-factor correction converter having an active rectifier stage with first and second rectifier transistors and first and second boost stages each with an inductor and transistor. An active rectifier controller circuit generates control signals for driving the rectifier transistors, respectively, on and off in accordance with an AC input voltage. A PFC controller circuit generates a pulse-width-modulated (PWM) control signal that is based on an output voltage of the boost stages and which is further based on a current sense signal representing the current passing through the active rectifier stage. A logic circuit generates a control signal for the transistor of the first boost stage and a control signal for the transistor of the second boost stage, based on the PWM control signal and at least one of the control signals for the rectifier transistors.
