Although GPS has been widely used, Loran-C is still highly desirable to be as an alternative PRS ( primary timing reference source) for an important part of a nation's infrastructure in Europe, Asia, and others areas, even in United States.

MCU get timing reference by zero-crossing detection. It compare the current speed feedback with the object feedback, and control the conduction phase and time using PWM mode to realize the stable speed-regulating of AC PG-motor.

单片机通过过零检测获取计时基准，比较当前转速反馈与目标反馈，采用脉宽调制PWM方式来控制三端双向可控硅开关器件的导通相位角及导通时间，实现交流PG电机的平稳调速。
