Abstract
This paper presents the design and analysis of a three-level hybrid boost converter based on a single-phase threelevel T-type inverter. The proposed converter can provide high energy conversion efficiency and high voltage gain capability withreduced component count. The pulse-width-modulation signals of the proposed converter are generated by comparing two dutycycles and two triangular carrier signals. The proposed converter consists of four power switches, four diodes, an inductor, andtwo capacitors. Detailed converter operations at each switching state with the corresponding voltage and current waveforms ofeach component are discussed. The functionality and performance of the proposed converter are verified through simulationand experimental results. © 2020 The Institution of Engineering and Technology.
