基于两级滞环的单相三电平逆变器滑模控制

In this article, we present a single-phase inverter controlled by a three-level sliding mode control. A simple first order sliding mode is designed to regulate the output voltage and it is implemented through a symmetrical two-level hysteresis band comparator. The hysteresis band of the comparator is dynamically adjusted to bound the switching frequency of the inverter. As a result, the desired vo...
