摘要: In this paper a two-stage high frequency AC-LED driver is designed and studied. The front-stage boost power-factor correction (PFC) circuit the rear-stage halfbridge series resonant inverter. lighting characteristics of AC voltage driving LEDs, effect LED to half-bridge are discussed. proposed design uses digital dimming control reduce chromaticity shift, connect LEDs as full-bridge rectifier simplify current sensing circuit. An 80-W with universal input (90~264 Vrms) implemented verify design. Experimental results show that variation coordinates (u', v') from brightness 100% 20% within 0.0023.
