摘要
提出了一种通过检测逆变器直流母线电流来获取实际三相输出电流的方法,阐述了该方法的原理,分析了死区时间对电流获取的影响以及解决方法。仿真表明获取的电流与实际检测的电流基本相同。
A way to obtain 3-phase output current through detection of DC bus current of inverter is proposed with the theory discussed. Influences on the current obtaining by dead time are analyzed and solutions are suggested. Simulations show that the obtained current is basically the same with the measured current.
