AC brushless generator combined diesel engine is much used for the power supply equipment due to the stability and maintenance. This paper presents a novel self-start circuit and CBS (current boosting system) for digital AVR in engine-generator system. At the starting of AC brushless generator, the output voltage from residual flux is very small. So, the AVR(automatic voltage regulator) should feed-forward the small voltage to increase the output voltage during building up the control power of AVR. And the CBS is used for keeping the constant output voltage at a sudden line-short accident of generator.
