摘要 交错Boost变流器(IBC)的效率受开关频率、Boost电感和输出电压的影响。通过解析法计算IBC的效率与上述三个参数的关系曲线,发现IBC的效率与开关频率、Boost电感具有非线性关系。首先,考虑功率因数的需求,对输出电压进行优化设计。然后,对总损耗或效率求偏导,得到最优开关频率和最优Boost电感。研制一台3.3kW IBC样机,其功率因数高于99%,满载效率可达97.6%。实验结果证实了所提出的设计方法的正确性。相比于传统设计方法,本文的设计方法可提高IBC的效率。

Abstract:The efficiency of interleaved Boost converter (IBC) is affected by the switching frequency, the boost inductor and the output voltage. The relationship curves between the efficiency of IBC and the above three parameters are calculated by analytical method. It is found that the efficiency of IBC has nonlinear relationships with the switching frequency/the boost inductance. Firstly, the output voltage is optimally designed considering the requirement of power factor. Then the optimal switching frequency and the optimal boost inductor are obtained by taking the partial derivatives of total loss or efficiency. A 3.3kW IBC prototype is developed. Its power factor is higher than 99%. Its full-load efficiency can reach 97.6%. The experimental results verify the correctness of the proposed design method in this paper. Compared with traditional design method, the proposed designed method can increase the efficiency of IBC.
