摘要
在分析了电压源型逆变器基本工作原理和相量关系的基础上,阐述了一种适合大功率逆变装置的复合控制方案。通过前馈与反馈控制技术,该方案实现了对系统输出电流的良好跟踪和简单控制。基于TMS320F240DSP构建全数字化试验系统,简化了系统硬件电路,提高了系统的可靠性。试验证实了复合控制方案的正确性和有效性,并显示出系统良好的动静态性能。
On the basis of the fundamental principal and pharos relation of a voltage-source inverter, a simple and novel compound control scheme for high-power inverters is represented in the paper. Using both feedforward and feedback control techniques, the scheme realizes well control for output current of voltage-source inverter. A fully digital experiment system controlled by TMS320F240DSP is introduced and the hardware is simplified. The results of experiment confirm the validity and present a good dynamic and quiet performance.
