A digital signal controller is used to design a permanent magnet gasoline generator to give rectified voltage output. This paper discusses the design of digital triggering software based on dsPIC30F2010. The complex phase shift trigger circuit is simplified through programming so that the controller can generate triggering signal. The experimental results show that the rectifying circuitry designed in the this method can be adapted to the input of wide ranges of voltage and frequency,guarantee a steady output voltage,and give a quick dynamic response at changeover of loads.
