Abstract

A power supply device of a lighting system using microwaves includes: a high-voltage transformer for converting general-purpose AC power into high-voltage AC power and outputting the high-voltage AC power; and a voltage multiplier unit for converting high-voltage AC power into high-voltage DC power , increasing the frequency of the DC power current, and outputting the DC power with the increased frequency. Since the frequency of electric power applied to the magnetron is increased to eliminate the flicker phenomenon, stable light can be radiated to the outer space.

Description
