Current Ripple Factor of a Buck Converter摘要电感和电容在 Buck 转换器中构成低通滤波器,此 LC 滤波器的转折频率总是设计得较低以便滤除开关纹波。常用的设计规则是,电感电流纹波被设计成电感平均电流的 30% 左右。本文引入表达电感纹波电流和其平均电流的比值的纹波系数的概念并由它导出电感尺寸的表达式。通过...
HYSTERETIC BUCK CONVERTER CONTROLLING OUTPUT RIPPLE VOLTAGE USING THERMISTORA hysteretic buck converter controlling an output ripple voltage using a thermistor includes a reference voltage part which supplies a plurality of reference voltages, a comparator which compares at least one reference voltage among ...
To reduce voltage ripple, filters made of capacitors (sometimes in combination with inductors) are normally added to such a converter's output (load-side filter) and input (supply-side filter).[1] Fig. 1: Buck converter circuit diagram. 3 A buck converter Switching converters (such as ...
