提出了一种新的全桥三电平LLC谐振变换器调制方法。采用这种调制方法，利用一谐波近似技术对变换器的电压增益进行了分析。因此，设计人员可以方便地计算转换器的参数。一个385V输入，225到378V/6.6kW输出的原型转换器显示出98.14%的峰值效率。
This paper proposes a novel modulation method of the full bridge three-level LLC resonant converter. The voltage gain of the converter is analyzed by First Harmonic Approximation technique using this modulation method. Therefore designers can easily calculate the converter parameters. A 385V input, 225 to 378V/6.6kW output prototype converter shows 98.14% peak efficiency.
