一种新型开关电容准谐振多电平逆变器
Novel Switched Capacitor Quasi-resonant Multi-level Inverter
摘要
Abstract
Aimed at the problems of current spikes and voltage fluctuations in the charging process of existing multi-level inverters,a novel quasi-resonant five-level inverter is proposed in this paper.A carrier-stacked pulse width modulation scheme is adopted,and the switched capacitor technology is combined with the traditional five-level inverter,which reduces the accumulated level at the previous stage and realizes the output of five-level voltage.In addition,the capacitor charging process and the series inductance resonate to eliminate current spikes and voltage fluctuations,while reducing the heating problem of the capacitor and prolonging the service life of the circuit.Finally,simulation verification is carried out,and results prove the correctness and feasibility of the scheme for the proposed inverter structure.关键词
