摘要：
Non-inverting buck-boost converter is a classical topology that can provide wide range of voltage conversion and bidirectional power transfer; thus, it is frequently used in industrial applications. However, the conventional hard-switching configuration can only reach a high voltage conversion ratio at the expense of low efficiency due to switching loss. In this paper, a soft switching non-inverting buck-boost converter is proposed. This converter uses a small film capacitor in parallel with the link inductor to provide zero voltage switching (ZVS) by allowing the link capacitor and link inductor resonate between power transfer states. This paper presents the principles of the operation of this converter and verifies its performance through simulation and experiment.
