成果简介	NOVELTY - The circuit has a rectifier connected to a two-output power factor correction (PFC) converter and a power control (PC) converter. Switches of the PFC converter and the PC converter are turned off, and diodes are turned on in a mode-4. A split capacitor (Co) maintains output power. A ripple cancellation approach eliminates ripple in LED load current, where harmonic distortion is reduced by smoothing action of an inductor (Lpfc), split capacitors (Co1-Co4) and the split capacitor aids in minimizing ripples in both current and voltage. The two output power Popfc is split into direct power (Pd(t)) and reprocessed power (Pr(t)). The direct power is sent directly to the LED load. USE - Single-phase LED driver circuit for use in a power factor LED driver circuit of a power control (PC) converter. Can also be used for a two-output power factor correction (PFC) converter. ADVANTAGE - The circuit improves efficiency in step-down conversion circuits by reducing power processing stages/steps, improves power factor with low input current THD as per the standards, eliminates ripple power to prevent the flickering effect on the illumination (light output), replaces electrolytic capacitors with long-lifespan capacitors without affecting power density and cost, optimizes power distribution with minimal semiconductor devices, and minimizes complex control circuits to reduce the cost and size of the driver circuit.
