Abstract
A power supply apparatus of a fighting system using microwave includes: a high voltage transformer for transforming a general AC power to an AC power of high voltage and outputting the high voltage AC power; and a voltage doubler unit for transforming the high voltage AC power into a high voltage DC power, increasing the frequency of the current of the DC power, and outputting the DC power having the increased frequency. Since the frequency of the power applied to the magnetron is increased to remove the flicker phenomenon, a stable light can be radiated to an external space.
