Claim 20:
21. The method of claim 20 wherein selectively transitioning the filter circuitry to the high capacitance first impedance state responsive to the determination that the duty cycle of the controllably conductive device falls within the first duty cycle range of from 25% to 75% further comprises:
selectively transitioning, by the control circuitry, a switch included in the filter circuitry to an electrically CONDUCTIVE state such that a first capacitance and a second capacitance are placed in electrical parallel with the controllably conductive device;
wherein the filter circuitry includes the first capacitance in electrical parallel with the switch coupled in electrical series with the second capacitance.
