摘要
传统的高速永磁起发电机(HSPMSG)一般采用三相桥式不控整流将输出交流电压变换为直流电压。采用这种整流方式得到的直流电压无法升高且不稳定,当需要输出较高的稳定直流电压时往往不能满足要求。因此本文利用Maxwell和Simplorer以及Simulink三款软件的联合仿真实现了HSPMSG的可控升压整流,总结了该整流系统对起发电机铁心损耗及转子涡流损耗的影响规律。结果表明SVPWM整流时会产生大量高次谐波,大幅增加了电机的铁心损耗及转子涡流损耗,且载波频率和幅值也会影响起发电机损耗大小。本文的结论对高温高速永磁起发电机的设计及转子温升计算具有有效的参考价值。
The traditional high-speed permanent magnet starter-generator(HSPMSG) generally adopts three-phase bridge uncontrolled rectification to convert the output AC voltage into DC voltage. The DC voltage obtained by this rectification method cannot be increased and is unstable, which often cannot meet the requirements when a higher stable DC voltage needs to be output. Therefore, this paper realized the controllable boost rectification of HSPMSG by using the co-simulation of Maxwell, Simplorer and Simulink, and summarized the influence of the rectifier system on the core loss of the generator and the eddy current loss. The results show that a large number of high-order harmonics will be generated during SVPWM rectification, which will greatly increase the iron core loss and rotor eddy current loss of the motor, and the carrier frequency and amplitude will also affect the generator loss. The conclusion of this paper has effective reference value for the design of high temperature and HSPNSG and the calculation of rotor temperature rise.
