摘要： An apparatus and a method for applying high voltage with high frequency. The apparatus includes a power generator for generating electric power with predetermined frequency, a voltage transformer receiving the electric power generated by the power generator, amplifying voltage of the electric power received, and applying the amplified voltage to a load, and an impedance matcher connected between the power generator and the voltage transformer to match impedances of the power generator and the voltage transformer to thereby transmit the electric power to the voltage transformer. High voltage with high frequency is obtained by transmitting the electric power generated from the power generator to the load without reflecting loss while conducting an impedance matching, and amplifying the voltage applied to the load using the coupled inductor and LC resonance.
