HIGH VOLTAGE GENERATION POWER APPARATUS

The present invention relates to a high voltage generation power device which controls that switches operate one among primary side coils of a transformer if output voltage is low and operate the primary side coils of the transformer if output voltage is high in a high voltage generation power device of flyback converter type of input and output parallel structures. The high voltage generation power device can drive that a variation range of the output voltage from prevailing voltage is generated from hundreds of V to several kV throughout a wide range. The high voltage generation power device comprises a first transformer wherein in an input power source and a first switch are connected between both ends of a primary side coil. The first transformer output voltage converted to a first output circuit connected to both ends of a secondary side coil according to on and off operations of the first switch. The high voltage generation power device comprises a second transformer wherein the input power source and a second switch are connected between both ends of the primary side coil. The second transformer outputs voltage converted to a second output circuit connected to both ends of the secondary side coil according to on and off operations of the second switch.
