A comparative analysis of shoot through control schemes for Z-source inverter

This paper presents a comparative analysis of different shoot through control schemes employed in Z-source inverters. Z-source inverter provides a single stage power conversion topology which can give both voltage buck and boost properties. This paper also gives an insight on the working of Z-source inverter by utilization of shoot through forbidden states. These states are utilized by implementing various control schemes namely Simple boost control (SBC), Maximum boost control (MBC) and Constant boost control (CBC). The design of impedance network, simulation of Z-source inverter using the different control schemes and their summary is put forward in this paper.
