Abstract

본 발명은 입력교류 전원의 변동에 상관없이 일정한 전원을 발생하기에 적당하도록 한 안정화 전원장치에 관한 것으로, 종래에는 입력 교류전원이 변동할시 출력 전원도 변동함로써 전원 공급이 불안정 하였으나, 본 발명에서는 입력 교류 전원의 변동에 따라 스위칭 수단으로 출력 전원을 제어하여 상기 결점을 개선시킬 수 있는 것이다.The present invention relates to a stabilized power supply device suitable for generating a constant power source regardless of fluctuations in the input AC power source. In the related art, the power supply is unstable because the output power also fluctuates when the input AC power source fluctuates. In the above, it is possible to improve the above-mentioned drawback by controlling the output power by a switching means according to the change of the input AC power.
