摘要
介绍了三相无环流交交变频控制系统设计的控制原理及其DSP控制系统硬件和软件的具体设计,并给出了在搭建的主回路平台上进行整体调试的结果。在其DSP控制系统的驱动控制下,三相交交变频器能输出频率为0～15Hz电流和电压波形,电流无环流死区时间为1.2ms,调试结果显示所研制的DSP三相交交变频数字控制系统具有较高的控制精度和实时性。
A DSP-based control system on a three-phase AC/AC cycloconverter without circulating current, including its hardware and software, has been developed. The results from the trial run are introduced in this paper. They show that the developed DSP-based control system has excellent control characters in both precision and real time. 0～15Hz current and voltage can be output by the cycloconverter, and the current dead-band can be reduced to 1.2ms.
