LED DRIVING CIRCUIT

摘要

PURPOSE: An LED(Light Emitting Diode) driving circuit is provided to reduce manufacturing costs by performing a constant current control of an LED channel through a transformer and a DC blocking capacitor. CONSTITUTION: An inverter switches input power. The inverter is an LLC resonant inverter, a full bridge inverter, or a half bridge inverter. A plurality of transformers are connected to the inverter and include a plurality of first windings and second windings. A plurality of rectifiers are connected to a plurality of second windings. A plurality of LEDs are connected to the plurality of rectifiers. A smooth capacitor(Cp) is arranged between the rectifier and the LED.
