Abstract
A circuit having a full bridge configuration with a single actively biased switching element. In one embodiment, the circuit is a ballast circuit having a full bridge inverter with one switching element. The bridge includes a diode coupled to the switching element such that the diode and the switching element are coupled between positive and negative rails of the inverter. The bridge further includes first and second capacitors coupled end to end across the positive and negative rails. The ballast circuit can be coupled to a rectifier/boost circuit having a boost inductor coupled to the inverter circuit.
