In this paper, the authors present a novel topology of Z-source inverter which can control the velocity of induction motor. The objective of their proposed topology is to improve the performance of Z-Source Inverter (ZSI) by reducing the voltage stress throughout the capacitors present in the impedance network. Therefore the voltage range of the Z-source capacitors is reduced which also reduces the cost of the proposed Z-source network topology. The ZSI is combined with an additional feature called buck and boost. Thus, it is otherwise known as buck-boost inverter. The proposed topology can effectively reduce the capacitor voltage which increases the efficiency of the Z-source circuit.
