The present invention relates to a high-voltage pulse generator and a low-temperature sanitization system using the same and, more specifically, to an ultrasonic humidifier, in which a low-temperature sterilization system is applied to perform low-temperature sterilization so that risk of accidents caused by high temperature is removed and an effective sterilization environment harmless to the human body is provided, thereby providing excellent cost performance and safe indoor humidity, and a driving method thereof. According to the present invention, the ultrasonic humidifier comprises: a housing; a water tank disposed inside the housing and containing water; a low-temperature sterilization system using a high-voltage pulsed electric field (PEF) to sterilize the water introduced from the water tank into a PEF chamber by using the high-voltage PEF; and an ultrasonic vibrator module including an ultrasonic vibrator and converting the water, which is sterilized while passing through the PEF chamber, into fine particles by using an ultrasonic vibration method to spray mist out of the housing. 본 발명은 고전압 펄스발생기 및 이를 이용한 저온 살균 시스템에 관한 것으로, 구체적으로는 저온 살균 시스템을 초음파 가습기에 적용하여 저온 살균함으로써 고온으로 인한 안전사고 위험성을 없애고 인체에 무해한 효과적인 살균 환경을 제공하여 가성비가 우수하고 안전한 실내 습도를 제공하는 초음파 가습기 및 그 구동방법에 관한 것이다. 본 발명에 따른 초음파 가습기는 하우징; 하우징 내부에 물이 수용된 수조; 상기 수조로부터 PEF 챔버로 도입된 물을 고전압 펄스 전기장(PEF)을 이용하여 저온 살균하는 저온 살균 시스템; 및 초음파 진동자를 구비하고 상기 PEF 챔버를 통과하면서 살균된 물을 초음파 진동방식으로 미세 입자화하여 미스트를 하우징 외부로 분무하는 초음파 진동자 모듈;을 포함하는 것을 특징으로 한다.
