Research on a 42 V automotive permanent magnet generator system based on field-circuit coupling method

文章采用场路耦合方法进行分析,利用商用Ansoft软件中的Maxwell 2D模块和Simplorer模块,采用场路耦合方法建立并研究了一台42V汽车用永磁发电机系统。对于不可控整流桥和全控整流桥,分别得出额定转速下不同负载对于蓄电池电压的影响,并得出不同转速下发电机铁耗和蓄电池电压。

The field-circuit coupling analysis of a 42 V automotive permanent magnet generator system was done. Based on the modules of the Maxwell 2D and Simplorer of the commercial software Ansoft, the 42 V automotive permanent magnet generator system was designed and researched by using the field-circuit coupling method. For uncentrolled rectifier bridge and fully controlled rectifier bridge, the output voltage of battery under different load at rated speed was presented. Besides, the iron loss and the output voltage of battery at different speed were given.
