Abstract

In this study, a low-temperature co-fired ceramic (LTCC)-based direct current (DC)-DC converter is proposed for reducing stray inductance and mitigating electromagnetic interference. The dominant radiating loop of the proposed LTCC-based DC-DC converter features a multilayer design, which helps suppress noise sources and reduce radiated emissions. The peak voltage of switching noise for the proposed DC-DC converter at the frequency of 500 kHz is approximately 8.98% lower than that of a conventional DC-DC converter. In addition, the radiated emission level of the proposed DC-DC converter is lower than that of the conventional DC-DC converter. In sum, the proposed LTCC-technology-based multilayer design reduces the peak voltage of switching noise and the radiated emission of the DC-DC converter.

基于ltcc的降低开关噪声和辐射发射的DC-DC变换器

在本研究中，提出了一种基于低温共烧陶瓷（LTCC）的直流（DC）-直流转换器，以减少杂散电感和减轻电磁干扰。所提出的基于LTCC的DC-DC转换器的主辐射回路具有多层设计，这有助于抑制噪声源并减少辐射发射。所提出的DC-DC转换器在500kHz频率下的开关噪声峰值电压比传统DC-DC转换器低大约8.98%。此外，所提出的DC-DC转换器的辐射发射水平低于传统DC-DC转换器。总之，所提出的基于LTCC技术的多层设计降低了开关噪声的峰值电压和DC-DC转换器的辐射发射。
