摘要

提出了一种新的死区时间补偿方法，能够对逆变器和负载特性进行自校正。实时执行的调谐依赖于通用补偿特性的参数选择。在参数搜索过程中，针对输出电流的谐波失真不断评估补偿质量。该方法对死区时间和其他寄生因素引起的谐波和线性失真都有很好的补偿效果。

Self-tuning dead-time compensation method for voltage-source inverters

A new method of dead-time compensation is proposed, capable of self-tuning to the inverter and load properties. The tuning, performed real-time, relies on parameter selection of a generic compensation characteristic. During the parameter search, the quality of compensation is being continuously assessed against the harmonic distortion of output currents. The method enjoys very effective compensation of both harmonic and linear distortion caused by dead time and other parasitic agents.
