Abstract
A digital high voltage generating apparatus and a method thereof are provided where a switching block controls voltage generated in a second side coil of a power transformer, a digital interface block provides a communication interface, and a digital controlling block controls intermittence of the switching block. The digital controlling block includes a switching section width computing unit for computing a switching section width of the switching block, a frequency counting unit for computing a count value corresponding to a half period of an output voltage of the digital controlling block, and a switching time point determining unit for determining a switching time point of the switching block based on the computed switching section width and the count value. Improved protection of a switch from damage, by a reduction in heat-generation quantity in the switch, is one of the achieved advantages.
