Abstract:
A power supply circuit, comprising:(a) a first rectifier for converting an AC current to DC current; (b) a starting circuit coupled to the first rectifier for providing a path for the AC current; (c) a gate drive arrangement coupled to the starting circuit; (d) a resonant converter circuit regeneratively controlled by the gate drive arrangement; and (e) a load circuit coupled to a resonant converter circuit for inducing the AC current in the load circuit, the load circuit, comprising: (1) a resonant inductance; (2) a resonant capacitance coupled to the resonant inductance; and (3) a load connected in parallel to the resonant capacitance, the load including, (i) a group of light emitting elements; and (ii) a capacitor coupled between the resonant capacitance and the group of the light emitting elements.
