Abstract: 본 발명은 광촉매를 활성화하기 위한 인버터로서 UV 램프를 점등하기 위한 안정기와 오존발생을 위한 고압 전원을 구성하기 위한 전원장치에 관한 것으로서, 풀 브릿지 인버터에서 전원의 양의 단자와 음의 단자에 사이에 직렬로 결선된 스위치 쌍의 중성점을 출력의 한 단자로 구성하고 입력커패시터의 중성점에 역시 또 다른 출력의 단자를 구성하여 하프 브릿지 형태로 인버터를 구성한 뒤에 주파수 제어를 하고 이 제어신호를 지연시킨 뒤에 위상차를 갖는 신호를 만들어서 또 다른 양의 단자와 음의 단자 사이에 있는 다른 스위치 쌍의 구동신호로 활용하여 풀 브릿지 인버터를 구성하고 제어하는 것을 특징으로 하는 풀 브릿지 인버터의 다출력 구조인 전원장치를 기술적 요지로 한다. 이에 따라 본 발명의 회로는 광촉매 활성화에 필요한 UV램프의 안정기와 오존발생을 위한 고압 직류 또는 교류전원을 하나의 인버터에서 동시에 얻으며 각 출력은 주파수와 펄스폭제어에 의해 독립적으로 가능하므로 부가적인 제어소자와 전력소자가 최소화되며 장치가 간단해지고 저가인 효과가 있으며, 또한 UV와 고압 방전에 의한 오존발생이 극대화되므로 바라는 광촉매 활성화가 극대화되는 효과가 있다.

CONSTITUTION: A pulse width control device of a full bridge inverter generates a control signal. An output of the full bridge inverter is controlled by the control signal of the pulse width control device. An output of a half bridge inverter is controlled by varying an operation frequency of a controller.

A multi-phase flyback and forward synchronous rectifying circuit includes two primary transformers(T1,T2 or T3,T4).

One of the primary transformers connected in serial is connected to a neutral point(n1) of a capacitor and the other of the two primary transformers is connected to a connection point(n2) between two primary switches(S1,S2 or S3,S4). Coils of two secondary transformers are connected to each other in serial. A connection point(n3) between the coils is connected to a negative terminal of an output capacitor(C0). The other terminal of each of secondary switches is connected to a positive terminal of the output capacitor.
