A hardware voltage regulation method of generator system is designed,which consisted of a the doubly salient electro-magnetic motor （DSEM）,two paralleling three-phase non-controlled bridge rectifiers and an analog voltage regulator. Firstly the machine characteristic is analyzed.Then based on a 18 kW DSEM and the output voltage negative feedback and the excitation current feed-forward, an analog voltage regulator is designed, but its principle and process operation is analyzed in detail.Finally experimental waveforms are given,and the results show that the design of the regulator circuit is simple and reliable, and can meet steady and dynamic performance of requirement.
