The Method of DC Bus Neutral-Point Voltage Reliable Equalization in Single-Phase Three-Level Inverters

摘要：

　　there is DC bus neutral-point voltage unbalance phenomenon in three level inverters, the existing literature for the study of the problem is mostly on three-phase systems, less research on single-phase systems.Based on the single-phase asymmetric inverter, this paper analyzes the causes of the DC bus neutral-point voltage unbalance, introduces a control method by changing three level switching modes.This method is simple, less depending on the model parameters and reliable.
