BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power supply for driving a dental x-ray camera having a comprehensive state detection, display, and notification function, and in particular, a filter and surge protection circuit (1), a PFC converter (2), a high voltage part electrolytic capacitor (3), and a DC. In a known dental X-ray imaging apparatus power supply having a DC converter (4) and a low pressure electrolytic capacitor (5), an ambient temperature detection sensor (6) and a high pressure and low pressure capacitor condenser temperature detection sensor (7) (8), the high voltage section and the low voltage section ripple current detection section (9) (10). High voltage section and low voltage section overcurrent detectors 11 and 12, high voltage section and low voltage section overvoltage detectors 13 and 14, condenser data storage section 15, capacitor driving time counting section 16, microcomputer 17, notification section (18) and a comprehensive state display unit 19 are further provided. Therefore, it is possible to predict the replacement and failure time of internal components such as electrolytic capacitors as well as the power supply device for driving the dental X-ray imaging apparatus itself, and to perform maintenance in advance, including failure of each component due to overvoltage and overcurrent. It is possible to prevent the risk of power failure and fire caused by the damage and explosion of the electrolytic capacitor due to the expiration of the life of the advanced electrolytic capacitor.본 발명은 종합상태 검출과 표시 및 알림 기능을 갖는 치과 X선 촬영기 구동용 전원공급장치에 관한 것으로 특히, 필터 및 서지 보호회로(1)와 PFC 컨버터(2), 고압부 전해 콘덴서(3), DC-DC 컨버터(4) 및 저압부 전해 콘덴서(5)를 구비한 공지의 치과 X선 촬영기 구동용 전원공급장치에 있어서, 주변온도검출센서(6)와 고압부 및 저압부 콘덴서 온도검출센서(7)(8), 고압부 및 저압부 리플전류 검출부(9)(10). 고압부 및 저압부 과전류 검출부(11)(12), 고압부 및 저압부 과전압 검출부(13)(14), 콘덴서 데이터 기억부(15), 콘덴서 구동시간 계수부(16), 마이컴(17), 알림부(18) 및 종합상태 표시부(19)를 더 구비시킨 것을 특징으로 한다.따라서, 치과 X선 촬영기 구동용 전원공급장치 자체는 물론
