Abstract :

This paper is devoted to the Quasi Z source network based DC Drive. The cascaded (two-stage) Quasi Z Source network could be derived by the adding of one diode, one inductor, and two capacitors to the traditional quasi-Z-source inverter The proposed cascaded qZSI inherits all the advantages of the traditional solution (voltage boost and buck functions in a single stage, continuous input current, and improved reliability). Moreover, as compared to the conventional qZSI, the proposed solution reduces the shoot-through duty cycle by over 30% at the same voltage boost factor. Theoretical analysis of the two-stage qZSI in the shoot-through and non-shoot- through operating modes is described. The proposed and traditional qZSI-networks are compared. A prototype of a Quasi Z Source network based DC Drive was built to verify the theoretical assumptions. The experimental results are presented and analyzed.
