| 摘 要： | 从能量的角度,对单级ＢＯＯＳＴ正激组合交换器在输入电感处于ＤＣＭ、输出电感处于ＤＣＭ和ＣＣＭ两种情形分别进行了稳态分析,获得了其中间电容电压、输出输入电压变比等的解析表达式,并用指数函数近似法,将上述表达式化简为非常便于使用的形式,实验结果证明了理论分析的正确性。

| Abstract: | From the view point of energy,the steady state performance of a single stage BOOST forward converter with input inductor in DCM and output inductor in both DCM and CCM are analyzed respectively.Equation describing the voltage on the intermediate capacitor and the voltage conversion ratio are obtained.By exponential approximation,we simplify the above equations into quit closed form expressions.Experiment results are in positive with the analysis. |
