摘要：

A new high-efficiency two-inductor boost converter is proposed in this letter. The proposed converter has topology variation characteristic by an additional single-pole double-throw relay. By operating a two-phase interleaved boost converter at ac low line input and single-boost converter with two series-connected inductors at ac high line input, the proposed converter efficiently utilizes two inductors and switching components. Therefore, the proposed converter can be optimally designed and its efficiency can be maximized at the respective ac input range. The proposed converter can be the most attractive solution for high-efficiency server power supply and other universal input power-factor-correction applications.
