Systems and methods for low-power lamp compatibility with a leading-edge dimmer and an electronic transformer
First Claim
1. An apparatus comprising a controller to provide compatibility between a load and a secondary winding of an electronic transformer driven by a leading-edge dimmer, wherein the controller is configured to:
- draw a first amount of power from the electronic transformer, the first amount of power comprising a maximum amount of a requested amount of power available from the electronic transformer, thus transferring energy from the electronic transformer to an energy storage device in accordance with the first amount of power;
transfer energy from the energy storage device to the load at a rate such that a voltage of the energy storage device is regulated within a predetermined voltage range; and
responsive to determining that the first amount of power is greater than a maximum amount of power deliverable to the load, decrease the requested amount of power.
