Classification: CPC H  Y | IPC H

Claim 18:
19. The method of claim 12, further comprising:
determining, by the control circuitry, a duty cycle of the controllably conductive device;
wherein selectively transitioning the filter circuitry between at least the first impedance state and the second impedance state based, at least in part, on the conductive state and the non-conductive state of the controllably conductive device further comprises:
selectively transitioning, by the control circuitry, the filter circuitry to a high capacitance first impedance state responsive to the determination that the duty cycle of the controllably conductive device falls within a first duty cycle range; and
selectively transitioning, by the control circuitry, the filter circuitry to a low capacitance second impedance state responsive to the determination that the duty cycle of the controllably conductive device falls outside the first duty cycle range.
