Abstract DC voltage balance control strategy is one of important parts in cascaded H-bridge rectifier control. Due to the good performance under certain conditions, proportional pulse compensation strategy for voltage balancing is a typical strategy. However, its balancing effect will be influenced by load current of the rectifier, which is difficult to realize self-adaptation for various load conditions. Therefore, an advanced voltage balance method based on the proportional pulse compensation strategy is proposed in this paper. The load current is introduced into the regulator to obtain good performance under different load conditions. Simulation and experimental results verify the proposed improved strategy.

Key words： Cascaded H-bridge rectifier voltage balance self-adaptive modeling analysis
