This paper presents simulation and experimental results of a quasi-Z-source inverter (qZSI) based bi-directional
DC/DC converter for supercapacitor (SC) interfacing. The bidirectional
capability provides both the charging and
discharging of the SC. During the charging mode the converter
operates as a conventional VSI performing the voltage buck
function, but during the discharging mode the converter
operates as a qZSI based step-up DC/DC converter performing
the voltage boost function. The proposed converter discussed
was tested in both operating modes - SC charging and
discharging. Theoretical assumptions are proved by the PSIM
simulation results and verified experimentally on a 500 W
laboratory prototype. The most important results obtained are
outlined.
