摘　　要：介绍了一种由电励磁双凸极电机(Doubly Salient Electro-magnetic Motor,简称DSEM)、三相不可控整流桥、模拟调压器构成的发电系统的纯硬件调压方法。简单说明了DSEM的原理及相应的数学模型,并以一台18kW DSEM为研究对象,根据输出电压负反馈、励磁电流前馈设计出一套模拟调压器。详细分析了模拟调压器的工作原理及过程。实验结果表明,所设计的调压电路简单可靠,能够满足DSEM作为发电机的稳态、动态性能要求。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.
