Abstract
A single-inductor dual-output (SIDO) buck-boost power factor correction (PFC)
converter operating in critical conduction mode is proposed in this paper. By
multiplexing a single inductor, each output of the SIDO buck-boost converter can be
regulated independently. Compared with a conventional two-stage multiple-output
converter, the SIDO buck-boost PFC converter benefits from significant overall cost
saving, small size, and light weight. Moreover, the efficiency of the SIDO buck-boost
PFC converter can be improved due to single-stage power conversion. The control
strategy and characteristics of the proposed converter are analyzed. The efficiency,
power factor, total harmonic distortion, and output accuracy are verified using the
experimental results.
