中文摘要:

为了优化单相全桥逆变器的直流链路上的电流纹波,本文设计了一种增强型的单相全桥逆变器及其控制策略,可有效降低直流链路电流纹波,并同时在交流输出端提供了优质的正弦电能。加强型全桥逆变器增设了一对额外的开关,通过设计了互补控制方案,可防止双倍频纹波电流流入逆变器的输入端,直流输入侧仅需提供输出功率的直流分量。最后,试验结果验证了所设计的增强型单相全桥逆变器的效果。

英文摘要:

In order to optimize the current ripple on the DC link of single-phase full-bridge inverter, an enhanced single-phase full-bridge inverter and its control strategy are designed to optimize the current ripple on the DC link. At the same time, it provides high quality sinusoidal energy at the AC output. The reinforced full-bridge inverter adds a pair of additional switches and is designed with a complementary control scheme that prevents double-frequency ripple current from flowing into the input of the inverter. The DC input side only provides the DC component of the output power. Finally, the experimental results verify the performance of the designed enhanced single-phase full-bridge inverter.
