摘要
从特定消谐的原理出发,建立了产生谐波的数学模型,分析了开关角与各次谐波之间的关系,得到产生谐波不宜采用查表法而应实时计算的结论.对于特定消谐式逆变器的实时控制,进行了硬件和软件方面的设计,并举例分析了实验结果.
Based on the principle of selected harmonic elimination(SHE),a math model of generating harmonic was founded,and the relations between the switch point and each times of harmonic were studied.The conclusion that the real-time calculate is more suitable than the check-table method when generate harmonic is gained.The hardware and software for real-time control of the SHE inverter were designed,and two examples of experiment result were analyzed.
