Sensorless neutral point voltage stabilization in three-phase four-wire converters

X Xu, G Tibola, JL Duarte - 2020 22nd European Conference …, 2020 - ieeexplore.ieee.org
This paper presents a midpoint voltage balancer (MVB) which provides neutral point voltage
stabilization to three-phase four-wire converters. The MVB consists of dual switching legs …

In the three phase four wire applications, three phases and neutral, often the loads are not
well balanced; hence there is a flow of current through neutral conductor. In these …
