The wound-field doubly salient generator (WFDSG) is receiving consideration for the field of industrial and aerospace/aviation, since it has the advantages of high robustness with simple structure and adjustable output voltage. In this paper, upon the analysis of generator structures, the features of three rectifiers that are suitable for WFDSG are analyzed in detail. The comparative research of WFDSG with hybrid half-bridge rectifier (HHBR), full-bridge rectifier (FBR), and half-bridge rectifier is presented by the finite-element method (FEM). Then, the load and no-load characteristics of WFDSG under the three rectifiers mentioned above are researched comparatively. The commutation overlap angles and total commutation output voltage losses of three rectifiers are deduced. The experiments of a 12/8-pole single armature-winding WFDSG (SAW-WFDSG) with an FBR and a 12/8-pole dual-armature-winding WFDSG (DAW-WFDSG) with HHBR prototypes have been performed. The FEM and experiment results shows that the SAW-WFDSG with FBR and the DAW-WFDSG with HHBR both have a good application prospect.

不同整流器的绕场双凸极发电机的对比研究


绕线场双凸极发电机（WFDSG）因其具有结构简单、鲁棒性高、输出电压可调等优点而受到工业和航空航天领域的关注。本文在分析发电机结构的基础上，详细分析了适用于WFDSG的三种整流器的特点。利用有限元方法(FEM)对WFDSG与混合半桥整流器(HHBR)、全桥整流器(FBR)和半桥整流器进行了比较研究。然后对WFDSG在上述三种整流器下的负载和空载特性进行了比较研究。推导了三个整流器的换流重叠角和总换流输出电压损耗。已经进行了带有FBR的12/8极单电枢绕组WFDSG（SAW-WFDSG）和带有HHBR原型的12/8极双电枢绕组WFDSG（DAW-WFDSG）的实验。有限元分析和实验结果表明，采用FBR的SAW-WFDSG和采用HHBR的DAW-WFDSG均具有良好的应用前景。
