In a power converter system, circuitry generates first and second PWM signals during a PWM cycle for controlling application of power to an inductor. Circuitry generates error signals having AC- and DC-components, the error signals being generated in response to indications of the power applied to or developed by the inductor. Circuitry generates a feedback control signal in response to the error signals. The first and second PWM signals are controlled in response to the feedback control signals.
