Abstract

High-voltage gain converter has a high-frequency use in some industrial fields, for instance, the fuel cell system, the photovoltaic system, electric vehicles, and the high-intensity discharge lamp. In order to solve the problem of the low-voltage gain of traditional boost converter, the double-boost converter with coupled inductance and doubled voltage is proposed, which connects the traditional boost converter in parallel. The voltage gain of the converter is further improved by introducing the voltage-doubled unit of the coupled inductance. Moreover, the clamp capacitor can absorb the leakage inductance in the circuit and reduce the voltage stress of the switch. In addition, two coupled inductors are magnetically collected; then, the loss of the core is analyzed under the same gain. The detailed analysis of the proposed converter and a comparison considering other topologies previously published in the literature are also presented in this article. In order to verify the proposed converter performance, a prototype has been built for a power of 200 W, input and output voltages of 12 and 84 V, respectively, and a switching frequency of 50 kHz. Experimental results validate the effectiveness of the theoretical analysis proving the satisfactory converter performance, whose peak efficiency is 95.5%.

基于电感耦合和磁集成的双升压变换器

高压增益变换器在燃料电池系统、光伏系统、电动汽车、高强度放电灯等工业领域有高频应用。为了解决传统升压变换器电压增益低的问题，提出了电感耦合双电压的双升压变换器，将传统升压变换器并联起来。通过引入耦合电感的倍压单元，进一步提高了变换器的电压增益。此外，钳位电容可以吸收电路中的漏电感，减小开关的电压应力。此外，两个耦合电感器被磁收集;然后，分析了在相同增益下铁芯的损耗。本文还详细分析了所提出的转换器，并考虑了先前在文献中发表的其他拓扑结构进行了比较。为了验证所提出的变换器的性能，已经建立了一个原型，功率为200 W，输入和输出电压分别为12和84 V，开关频率为50 kHz。实验结果验证了理论分析的有效性，转炉性能良好，峰值效率达95.5%。
