Abstract: A power converter includes a power converter circuit and a microcontroller that controls the power converter circuit. The microcontroller includes a power control unit and a processing unit. The power control unit adjusts the switching frequency of the power converter circuit based on thresholds of a resonant capacitor of the power converter circuit. The power control unit also generates event signals indicative of breaches of the thresholds by the resonant capacitor. When the processing unit receives an event signal from the power control unit indicative of a breach of one of the thresholds by the resonant capacitor, the processing unit determines whether the switching frequency falls outside a defined range based on the event signal. In response to determining that the switching frequency falls outside the defined range, the processing unit instructs the power control unit to clamp the switching frequency of the power converter circuit.

Abstract: A multiple-output integrated power factor correction system includes, for example, a processor that is formed in a substrate and is arranged to monitor each voltage output of two or more output stages of a power supply and in response to generate an individual voltage error signal for each monitored output stage. A combined output voltage error signal is generated in response to each of the individual voltage error signals. The voltage input to the power supply and the total inductor current of the power supply are monitored and used to generate a combined output voltage control signal in response to the monitored input voltage total inductor current as well as the combined output voltage error control signal. Each individual output voltage control signal for each monitored output stage is generated in response to each of the respective generated individual voltage error signals.
