摘要
本文针对电力电子电路中谐波信号过零检测不准确的问题,提出一种带有相位补偿功能的过零检测方法。计算机仿真表明,此种方法可以有效地提高过零检测的准确性。
A method of across-zero detecting with phase delay compensation is presented with the purpose of solving the problem caused by the harmony wave in power electronic circuit. The simulation shows that this method improves the accuracy of the across-zero detecting system.
