摘要
近年来，宽电压范围 DC/DC 转换器已广泛应用于电信电源、太阳能发电和电动汽车充电器等领域。在此基础上，本文提出了一种新型宽输入电压多谐振转换器。与传统的 LLC 转换器相比，所提出的转换器在欠谐振和过谐振区域都能将输出电压维持在较窄的频率调节范围内。因此，无需额外的开关元件或复杂的控制策略，就能实现宽电压范围。本文介绍了拟议转换器的拓扑结构和相应的工作原理。此外，还建立了考虑基波的等效模型，并详细分析了谐振参数对电压增益特性的影响。基于这些考虑，设计了谐振参数。最后，建立了一个 500 W 的实验平台，以验证所提转换器的有效性和可行性。
A triple-LC-based DC/DC converter with wide input voltage gain in both under-resonance and over-resonance frequency regions
In recent years, wide voltage range DC/DC converters have been widely used in telecom power, solar generation and electric vehicle charger applications. Based on this, a new multi-resonant converter with wide input voltage is proposed here. Compared with the traditional LLC converter, the proposed converter can maintain the output voltage within a narrow frequency regulation range in both under-resonance and over-resonance areas. Thus, a wide voltage range can be realized without additional switch components or complex control strategies. The topology and the corresponding working principle of the proposed converter are introduced. In addition, the equivalent model by considering the fundamental wave is established and the influence of the resonance parameters on the voltage gain characteristic is analysed in detail. With these considerations, the resonance parameters are designed. Finally, a 500 W experiment platform is established to verify the effectiveness and feasibility of the proposed converter.
