本文研究了零电流软开关（ZCS）PWM升压DC-DC变换器的可行性。这种类型的软开关DC-DC升压变换器是有效的，特别是基于IGBT的DC-DC变换器，由于其换流过程独立于尾电流过渡。通过实验数据比较了ZCS-PWM DC-DC变换器拓扑的性能，并与硬开关拓扑进行了比较，详细研究了有源边缘谐振单元的实际可行性，包括损耗分析。
This paper presents the feasibility study of Zero Current Soft-switching (ZCS) PWM boost DC-DC converters with auxiliary lossless active edge-resonant cells. This type of soft-switching DC-DC boost converters is effective especially for IGBTs-based DC-DC converter due to its commutation process independent on the tail current transitions. The performances of ZCS-PWM DC-DC converter topologies are compared by experimental data, referring to the hard-switching one, and detailed investigation including loss analyses is described in order to demonstrate the practical feasibility of the active edge resonant cells.
