基于DSP的离网型永磁同步发电机电压调节器

Design of voltage requlator in off-grid permanent magnet synchronous generator based on DSP

针对目前离网型永磁同步发电机输出电压不稳定及难以调节的问题,先将输出电压整流成直流电压,再将直流电压逆变为交流电压输出。逆变电路采用SPWM算法,并以DSP作为控制核心。经过整流、逆变后,发电机的输出电压稳定,并且能对输出电压方便地进行调节。

As to the problem of off-grid permanent magnet synchronous generator output voltage was not stable and difficult to adjust, this paper transformed the output voltage into a DC voltage, then the DC voltage was transformed into AC voltage. The algorithm of SPWM with DSP as the controller was used in inverter circuit. Though rectifiers and inverters, the generator output voltage can be stable and conveniently regulated the output voltage.
