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.
