Abstract

This research work presents a novel control structure of Z-source inverter (ZSI) for fuel cell (FC) Applications with the help of closed loop PI regulator. The Z-source concept is applicable to AC-DC-AC-AC conversions. So, the ZSI have more advantages compared to traditional voltage source and current source topologies. Here the Z-source topology employed for DC-AC conversion for fuel cell application. The fuel cell energy connected to Z-source inverter topology, the output of inverter connected to linear R-load. The entire proposed closed loop PI -ZSI system implemented and tested in MATLAB-SIMULINK software. And also provided comparison between conventional open loop ZSI systems with closed loop PI-ZSI system. By verifying these results, PI-ZSI system provides good response and improves system stability.
