摘要

本文提出了一种高增益模块化多电平dc-dc变换器拓扑结构。与传统的模块化多电平升压变换器相比，该变换器提供了额外的控制自由度和更高的稳态电压增益。该变换器工作在连续导通模式下。提出了一种基于状态空间平均建模的小信号模型。此外，本研究还涵盖了工作在连续导通模式下的高增益模块化多电平dc-dc变换器的小信号和稳态分析。将该变换器的性能与传统的模块化多电平dc-dc变换器进行了比较。为了验证这一设计，在1 kW, 48 V到288 V的变换器系统上进行了仿真。最后，通过仿真结果验证了该转换器的有效性。

A high-gain modular multilevel DC-DC step-up converter

In this paper, a high gain modular multilevel dc-dc converter topology is proposed. As compared with the conventional modular multilevel step-up converters, the proposed converter offers an additional degree of control-freedom and higher steady-state voltage gain. The proposed converter operates in continuous conduction mode. A detailed small-signal modeling for the proposed converter based on state-space average modeling is presented. In addition, this study covers both the small-signal and steady-state analysis for the high gain modular multilevel dc-dc converter operating in continuous conduction mode. The performance of the proposed converter is compared with conventional modular multilevel dc-dc converter. To confirm this design, simulations have been carried out on a 1 kW, 48 V to 288 V converter system. Finally, the validity of the converter is verified by simulation results.
