A driver circuit for powering a load is disclosed. The driver circuit includes a self-oscillating half-bridge circuit, a resonant driver in electrical communication with the self-oscillating half-bridge circuit, and a DC voltage supply in electrical communication with the resonant driver. The self-oscillating half-bridge circuit is configured to generate a high-frequency AC signal. The resonant driver is configured to limit a current of the high-frequency AC signal and produce a limited output voltage based on the high-frequency AC signal. The DC voltage supply is configured to rectify the limited output voltage into a DC output voltage including a substantially constant current for powering the load. |
