摘　　要：介绍了一种双电感boost半桥隔离型三电平变换器。该变换器由变压器隔离,其初级采用双电感boost型变换器结构,次级采用半桥变换器结构。分析了该变换器的工作原理,给出了理论上的工作波形,推导了相关公式,设计了控制策略。仿真结果表明,在一定条件下,该变换器可以降低开关应力,提高输出电压。A three-level converter based on the two-inductor isolated half-bridge boost converter is discussed in this paper. It is isolated by the transformer, with the two- inductor boost converter as its primary side and the half-bridge converter as its secondary side. The operation principle is investigated, theoretical idealized waveforms are given, relevant formulas are derived, and the control strategy is also designed in the paper. The results of the stimulation indicate that the converter can reduce the voltage of switches and boost the voltage greatly in certain conditions.
