基于DSP的交流励磁电源设计

Design of the AC Excited Generator Excitation Power Supply Based on DSP

阐述了交流励磁电源DSP硬件设计和软件设计过程;进行了PWM波输出实验。实验证明输出PWM波稳定可靠,畸变率小,对直流母线电压进行了仿真,实验研究证明该励磁电源能跟随负载变化而直流母线电压稳定可靠,进一步深入研究后可用于交流励磁发电系统。

The design process of minimum systems and PWM modulation of DSP for excitation power supply were described, and a PWM wave output experiment was made. Experiments show that the PWM wave output is stable and reliable. Simulation studies of the DC bus voltage of the excitation power show that it can follow the load changes and stable and reli- able. Waveform distortion rate low and can be used for AC excitation power system after advanced study.
