Abstract:
A controller for a power factor correction boost converter comprising:a. first means for controlling charging of a first inductor with energy from an alternating-current power supply and for controlling discharging of the first inductor into an output capacitor wherein the first means operates in accordance with a first clock signal;b. second means for controlling charging of a second inductor with energy from the power supply and for controlling discharging of the second inductor into the output capacitor wherein the second means operates in accordance with a second clock signal and wherein the second means is coupled to the first means; andc. means for forming a synchronizing output signal for synchronizing operation of a pulse width modulation converter with the power factor correction boost converter wherein the synchronizing output signal is synchronous with at least one of the first clock signal and the second clock signal.
