Switched mode power supply with power factor control

A circuit, comprising:

• a dual-boost power-factor correction (PFC) converter including an active rectifier stage with a first rectifier transistor and a second rectifier transistor, a first boost stage with a first inductor and a first transistor, and a second boost stage with a second inductor and a second transistor;
• an active rectifier controller circuit configured to generate a first control signal and a second control signal for driving the first rectifier transistor and the second rectifier transistor, respectively, on and off in accordance with an AC input voltage;
• a PFC controller circuit configured to generate a pulse-width-modulated (PWM) control signal based on an output voltage of the first and the second boost stages and further based on a current sense signal representing the current passing through the active rectifier stage;
• and
• a logic circuit configured to generate a third control signal for the first transistor of the first boost stage and a fourth control signal for the second transistor of the second boost stage, based on the PWM control signal and at least one of the first and the second control signals.
