摘要
本文分析了导致逆变电源输出变压器直流偏磁的原因,在此基础上提出了一种抗直流偏磁的对策——数字PI电压积分调节法,通过仿真实验证明了该种方法的可行性和有效性。
The causes of the flux imbalance in the output transformer of the inverter were analyzed in this paper. A corresponding approach of avoiding flux imbalance—digital PI voltage integral is introduced. The practicability and effectiveness of the approach are proved by simulation.
