Abstract

This paper presents the solar power based maximum boost Z-Source Inverter (ZSI) for Uninterruptible Power Supply (UPS) application. The concept of maximum boost Z-source can be applied to all dc-to-ac, ac-to-dc, ac-to-ac, and dc-to-dc power conversions. The maximum boost ZSI topology overcomes the limitations of conventional boost converter interfaced with Voltage Source Inverter (VSI). By this new topology, solar power is utilized properly with minimum controller circuit. The proposed system can maintain the desired output voltage through proper switching of maximum boost Z-source inverter. A prototype model of solar powered 400VA UPS system is designed and implemented. The entire system is simulated using SIMULINK and its performance is analyzed with experimental results.
