Abstract

This paper proposes a control technique of soft switching operation or quasi-resonance intrusion along with slope compensation in a conventional Hard Switched Boost Converter (HSBC) to realize the proposed Soft Switched Boost Converter (SSBC) under Current Mode Control (CMC for a part of the switching cycle to mitigate intermittent instabilities, Electro Magnetic Interference (EMI) and to extend the stable operating region. An intensified stability analysis was performed and the viability of the converter was tested with the effect of diversified periodic interference signals and comparative analysis was made between HSBC and SSBC. The impact of switching manifold due to the increase in modes of operation by soft switching was considered. The system dynamics were captured using MATLAB/Simulink, and the results were validated using appropriate experimental setup results. Furthermore, to demonstrate the proposed control technique’s improved stability, theoretical bifurcation analysis was performed in SSBC as Power Factor Correction (PFC) converter.

利用软开关和斜率补偿技术增强 SSBC 的稳定性并降低 EMI

本文在传统的硬开关升压转换器（HSBC）中提出了一种软开关操作或准谐振侵入的控制技术，同时还提出了斜坡补偿，以实现在电流模式控制（CMC）下部分开关周期的软开关升压转换器（SSBC），从而缓解间歇性不稳定性、电磁干扰（EMI）并扩大稳定工作区域。在多种周期性干扰信号的影响下，对转换器进行了强化稳定性分析和可行性测试，并对 HSBC 和 SSBC 进行了比较分析。此外，还考虑了软开关增加运行模式对开关歧管的影响。使用 MATLAB/Simulink 捕捉了系统动态，并使用适当的实验设置结果对结果进行了验证。此外，为了证明所提出的控制技术提高了稳定性，还对作为功率因数校正（PFC）转换器的 SSBC 进行了理论分岔分析。
