| 摘 要： | 针对传统发电机整流系统谐波含量大，功率因数低的特点，为永磁同步发电机设计了一套PWM整流系统，通过电流前馈解耦控制，实现有功无功解耦，实现发电机侧单位功率因数运行。实验结果验证了该控制方案的可行性，可有效减少发电机电流谐波含量，并能在发电频率较大范围变动时仍能保持系统稳定运行。

| Abstract: | Due to low input power factor and high-harmonic of conventional generator-rectifier system, a PWM rectifier is designed for a permanent magnet synchronous generator（PMSG）. Through current feed-forward control strategy, this paper implements the active power and reactive power decoupling and unity power factor The experimental results validate the feasibility of the control, which can achieve low-harmonic and unity power factor Within a large range of frequency change, the system can also keep stably. |
