摘要 该文针对一类新型的三电平DC-DC 变换器进行详细的研究,该电路使用一个双向开关构造中间电平,大大简化原有多电平电路的复杂程度,使多电平电路有可能被用于中低功率场合。通过将该电路与传统的全桥电路相比较研究可以发现,该电路具有输出谐波含量小的特点,可以非常有效减小输出无源滤波元件的体积和重量。该文详细探讨了这类新型三电平DC-DC 变换电路的电路结构和工作原理,并进行了实验研究。实验结果证明该电路原理正确,可以正常工作。 Novel three-level DC-DC converters researched, which are new kind of three-level DC-DC converters applied to middle or small power conversion, and utilize bi-directional switch modules to provide the middle electric level to decrease the harmonic content in output waveform. The configuration and operational principles of the novel converters are discussed. Comparisons between these new converters and traditional full bridge DC-DC converters are performed, and the results show that the weight and volume of passive component in the investigated converters are much smaller than those in conventional full bridge DC-DC converters. Experiments are done to confirm their working principles.
