Abstract
A single-inductor multi-output (SIMO) buck boost power factor correction (PFC) converter working under critical conduction mode is proposed here.Different output voltages can be generated with the help of this converter. Only one inductor is required.Compared with a conventional two stage multiple output converter,the SIMO converter benefits from significant over-all cost saving, small size, and light weight By multiplexing a single inductor, each output of the buck boost converter can be regulated independently.Moreover, the effciency of the SIDO buck boost PFC converter can be improved due to single-stage power conversion. These converters are the most efficient and cost effective solution for multiple output power supplies.
