Abstract
Exemplary embodiments provide for power conversion for solid state lighting coupled to a first switch, such as a dimmer switch. An exemplary apparatus includes a switching power supply and a first adaptive interface circuit. The first adaptive interface circuit may include a resistive impedance coupled in series to a reactive impedance. The apparatus may also include a second adaptive interface circuit including a second switch coupled to the reactive impedance. The second adaptive interface circuit is configured to conduct current from the first switch in a second current path. At least one of the first and second adaptive interface circuits may be configured to damp oscillation when the first switch turns on.
