The purpose of this paper is to present AC driver and protection circuits of Light Emitting Diodes. For the presented circuits, AC power source can be applied to drive LED without further conversion stage and the circuits provide failure indication and protection. The presented system consists of a full-bridge LED modules, power device and control circuit for dimming control and protection circuits. The LED modules for each upper and low arm are with pulse-width modulation control in every half… CONTINUE READING
