This paper presents a bi-directional quasi-Zsource
inverter (qZSI) based DC/DC converter for
supercapacitor (SC) interfacing in high power applications.
In the SC charging mode the proposed converter acts as a
conventional VSI based step-down converter, but in the
energy recovery mode it acts as a qZSI-based step-up
DC/DC converter. The paper analyzes and discusses the
operation of the converter in the SC charging mode. The
analysis of the static model of the converter as well as the
Bode diagram are presented. Theoretical results are verified
by experimental results on a 500 W prototype converter.
