| Abstract: | 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 |
