Abstract: In accordance with embodiments of the present disclosure, a system and method for providing compatibility between a load having a reactive impedance during steady-state operation and a secondary winding of an electronic transformer driven by a leading-edge dimmer may include a first circuit and a second circuit. The first circuit may cause the load to have a substantially non-reactive impedance when the first circuit is enabled. The second circuit may enable the first circuit to cause the load to have the substantially non-reactive impedance during a duration of time following start-up of the electronic transformer and disable the first circuit after the duration such that the load has the reactive impedance during steady-state operation of the load.
