摘　　要：永磁同步发电机(PMSG)具有效率高、结构简单等优点,越来越得到重视和研究。直接转矩控制(DTC)具有控制结构简洁,对电机参数依赖少,转矩动态响应迅速等特点,在发电领域中得到了应用。这里以TMS320F2812DSP为核心,结合PMSG DTC的特点,设计了一套功能完善、实时性好的270 V高压直流发电系统。实验结果表明,硬件系统工作可靠、控制响应快。Permanent magnet synchronous generator（PMSG） has the advantages of high efficiency,simple structure and so on.It is more paid attention to be researched.Direct torque control（DTC） has many merits,such as simple control structure, requiring only stator resistance, fast torque dynamic response etc, so it is also applied in generation system. Using TMS320F2812 DSP as the core, and combining the feature of the DTC, a 270 V high voltage direct current generation systerm is designed which has multi-functions and good real-time performance.The experimental results show that the hardware platform operates reliably and has fast control speed.
