摘要
提出了一种实用的输入滤波电容量最优设计方法。运用该方法，根据变换器拓扑、工作模式、输入功率、输入电压、开关频率、占空比，依据输入电压纹波等指标要求，可以定量计算出符合指标要求的、满足多种设计边界条件的输入滤波电容器的容量参数。
A practical optimal design method of input filter capacitor is presented.According to the converter topology, work mode, input power,input voltage, switching frequerey, duty ratio, based on the input voltage ripple and other requirements,the input filter capacitance parameters are quantitatirely calculated to meet a variety of bounolary condition.
