摘　　要：详细介绍了基于单片机的内燃机车新型辅机控制装置的设计,采用数字PID控制方法调节辅助直流发电机励磁绕组的电流,实现恒压限流控制,结构设计方面强化了MOS管散热与电磁兼容性能,具有输出电压稳定、各种保护功能全面、调试与扩充升级方便等优点。New design of auxiliary generator controller based on single-chip microcomputer for diesel locomotive was introduced in detail. Constant voltage and current limit of auxiliary generator exciter winding was realized by mathematical PID control, and heat dissipation of MOSFET and electromagnetic compatibility were considered through shape designed. The new controller has the advantages of voltage stabilization, full protect function and easy debugging and easy upgrading.
