The present invention relates to an IPL apparatus that is used as a hair removing machine or cures skin ailments by periodically irradiating Xenon lamp light on the users skin, the IPL apparatus comprises: a double-voltage unit which has a double-voltage capacitor, and outputs a high voltage by superposing an inputted supply voltage with a voltage charged in the double-voltage capacitor a charging capacitor which charges energy for turning on a Xenon lamp by accumulating electric charges supplied from the double-voltage unit a reference voltage generator which sets a charging voltage level charged in the charging capacitor and a switch unit which is positioned between the double-voltage unit and the charging capacitor, and switches on and off the movement of the electric charges to the charging capacitor from the double-voltage unit by setting an output of the reference voltage generator to a control signal.
