| Summary: | 碩士 === 中華大學 === 電機工程學系碩士班 === 91 === It applies a principle of switch-mode-power-supply in the thesis, Ni-Cd-Battery of 4.8 Volts (DC) converters to 325 Volts (DC). This is driving power supply of UV Flame Detector. After adding a concave mirror that rotates the UV sensor, it increases distance of detection and supplements a defect that angular sensitivity of UV sensor is one-side. In addition, in order to detect exactly, it must be add a chopper. I make a quenching circuit that replaces chopper of mechanization.
