Zusammenfassung: | PURPOSE: An LED driving AC-DC converter for a light capable of minimizing the capacity of a filter capacitor is provided to minimize the capacity of a filter capacitor while securing the high power factor, the high efficiency, and the output performance. CONSTITUTION: An LED driving AC-DC converter for a light capable of minimizing the capacity of a filter capacitor includes a PFC insulating part (10) which performs insulation from the PFC of the AC input current, raises the voltage of a first side using the duty ratio to a transformer, and makes the phase of the AC input current the same as the voltage; and a voltage regulator (20) which stabilizes V1, the DC output voltage to an LED load, at a certain voltage. [Reference numerals] (10) PFC insulating part; (20) Voltage regulator; (30) LED load |
