Maximum constant boost control for QZSI in a fuel cell system

Fuel cell systems are a type of DG systems and can offer the prospect of supplying the world with safe, clean, efficient, sustainable electrical energy. In order to control of fuel cell systems, in this paper proposed QZSI and maximum constant boost control. The quasi-Z-source inverter (QZSI) is similar to the ZSI. The QZSI has been developed which feature several improvements and no disadvantages when compared to the ZSI. Simulation results will be presented to demonstrate the new features.
