专利内容由知识产权出版社提供专利名称：Buck-boost converter发明人：Frederic Choquet申请号：US15232361申请日：20160809公开号：US10355596B2公开日：20190716专利附图：摘要：A buck-boost converter and a method are presented. The buck-boostconverter comprises an inductor, a buck converter, and a boost converter. The buckconverter controls switches according to a buck duty cycle, whereas the boost convertercontrols switches according to a boost duty cycle. The converter contains a voltagefeedback loop for regulating an output voltage of the converter. A buck comparatorgenerates the buck duty cycle signal by comparing the error voltage with a ramp voltage.A boost comparator generates the boost duty cycle signal by comparing a boost errorvoltage with the ramp voltage, wherein the boost error voltage is indicative of a sum ofthe error voltage and an offset voltage and the boost ramp voltage is indicative of a sumof the ramp voltage and the offset voltage. There is a duty cycle feedback loop foradjusting the buck and boost duty cycles.申请人：Dialog Semiconductor (UK) Limited地址：London GB国籍：GB代理机构：Saile Ackerman LLC代理人：Stephen B. Ackerman更多信息请下载全文后查看
