摘要
针对双级矩阵变换器(TSMC)特殊的换流问题,研究了一种可使TSMC安全可靠工作的换流策略。分析了四步换流原理,给出了实现框图,并最终搭建了一台基于英飞凌单片机XE164+CPLD的实验样机,对换流策略进行了实验验证。实验结果表明,四步换流是一种切实可行的换流措施,不仅能实现TSMC安全可靠换流,且对TSMC输入输出性能无影响。
Aiming at the special commutation problem of two-stage matrix converter (TSMC), a commutation strategy is studied, which makes TSMC work safely and reliably. The commutation principle was deduced with an experimental setup. At last, an experimental prototype was established based on XE164+CPLD. The experimental results indicate that the four-step commutation is a safe and reliable commutation method, which would not affect the input and output performance, but also makes TSMC work safely and reliably.
