摘要
介绍了一种采用单端反激变换拓扑设计制作高压直流开关电源的方法,分析了电路原理和设计中的特殊问题以及解决措施,提出了工艺结构设计中应注意的问题制作出的电源由12V蓄电池供电,输出有500V,1000V,1500V,2000V,2500V共5档供选具有体积小,重量轻,响应快,可靠性高等特点,并成功应用于绝缘电阻测试仪。
A high-voltage switching power supply was designed and fabricated using single end flyback topography. The principle and particular problems of the circuit are analysed, and solutions arc also proposed. The main problems about cou-figuration are discussed. The fabricated device is inputed by DC 12V, and it can output 500 V, 1 000 V, 1 500 V, 2 000 V or 2500V. It features small volume, light weight, last speed and high reliabrhty. and it is used in insulation resistance meter
successfully .
