摘要
本文分析了正弦波逆变电源中工频变压器直流偏磁问题产生的原因 ,提出一种在正弦信号波中加入直流调整量来抑制直偏的新方法。通过在 5 k VA UPS中的应用 。
By analyzing the causes of the flux imbalance in the utility frequency transformer of sine wave inverter, a new approach of avoiding flux imbalance is introduced in this paper by applying an adjusting voltage into the sinusoidal signal. The practicability of the approach is proved by employing it in a 5kVA UPS system.
