摘　　要：介绍了采用零电流开关变流技术研制8K机车904#开关电源板,设计采用了模块化结构,从而提高了电源板使用的可靠性。通过微处理器软件编程技术实施对输入、多输出电源进行管理,不仅提高了对电源故障监控的准确性和响应速度,而且提高了对电源故障维修处理的效率。Domestic 904^# Switch- power- board of the 8K locomotive is designed to adopt zero- current- switch converting technique, and it is designed to adopt modular structure to improve the reliability. Using the microprocessor software programming technique, it can manage input/multi - output power. This not only improves the veracity and response - speed of power failure monitoring, but also increases the efficiency of power failure mainterrance
