A Novel Switching Loss Analysis of Coupled-Inductor Impedance-Source Inverters

IECON 2021 – 47th Annual Conference of the IEEE Industrial Electronics Society, 2021
The Impedance-source inverters have been proposed for integrating voltage-boost, buck and inversion into a single stage with shared functionalities and hence lesser active switches. Recently, some of them even have coupled inductors included for raising gain, while retaining high dc-link utilization without extra components.
