摘要
In accordance with embodiments of the present disclosure, an apparatus may comprise a controller to provide compatibility between a load and a secondary winding of an electronic transformer. The controller may be configured to operate a single-stage power converter in a first power mode for a first period of time, such that the single-stage power converter is enabled to transfer energy from the secondary winding to the load during the first power mode and operate the single-stage power converter in a second power mode for a second period of time prior to the first period of time, such that the single-stage power converter is enabled to transfer energy from the secondary winding to the load during the second power mode, wherein the first power mode and the second power mode occur within a half-line cycle of an electronic transformer secondary signal present on the secondary winding.
