Document Type and Number:
WIPO Patent Application WO/2017/183813
Kind Code:
A1
Abstract:
The present invention relates to an IPL driving circuit and an IPL device having the same. The present invention is characterized in that one driving circuit is used for charging up to three times a commercial power peak voltage when used in a commercial power source having 110V and up to two times the commercial power peak voltage when used in the commercial power source having 220V. An IPL driving circuit of the present invention comprises: a diode and capacitor selection operation unit, a first terminal of which is connected to a first terminal of the commercial power source, and which operates as a first capacitor in the commercial power source having a first voltage and a first diode in the commercial power source having a second voltage; and an input voltage responsive diode which is connected between a second terminal of the diode and capacitor selection operation unit and a second terminal of the commercial power source, and which operates as a diode in the commercial power source having the first voltage and operates as an open circuit having an infinite resistance in the commercial power source having the second voltage.
