Abstract
A driver circuit for powering at least one light emitting diode (LED) in a dimming application is disclosed. The driver circuit includes an input for connection to a source of dimmed AC power and a rectifier for converting the dimmed AC power from the input into DC power. The driver circuit also includes a voltage bus filter for smoothening the DC power from the rectifier. The voltage bus filter includes at least one capacitor. The driver circuit also includes a feedback circuit in electrical communication with the rectifier. The feedback circuit causes the rectifier to continuously draw current from the inputs of the driver circuit.
