Systems and methods for low-power lamp compatibility with an electronic transformer
First Claim
1. An apparatus for providing compatibility between a load having a reactive impedance and a secondary winding of an electronic transformer, comprising:
- a power converter for transferring electrical energy from the secondary winding to the load; and
a circuit for charging an energy storage device coupled to the power converter following start-up of the electronic transformer in order to increase a voltage of the energy storage device to at least a voltage level sufficient for the power converter to enter steady-state operation, after which the power converter begins receiving electrical energy from the secondary winding of the electronic transformer.

Abstract
In accordance with systems and methods of the present disclosure, an apparatus for providing compatibility between a load having a reactive impedance and a secondary winding of an electronic transformer may include a power converter and a circuit. The power converter may be configured to transfer electrical energy from the secondary winding to the load. The circuit may be configured to charge an energy storage device coupled to the power converter following start-up of the electronic transformer in order to increase a voltage of the energy storage device to at least a voltage level sufficient for the electronic transformer to enter steady-state operation.
