Simulation and Analysis of Z-Source Inverter Fed PMBLDC Motor

This paper deals with the simulation and operation of PMBLDC Motor drive system with Z-Source Inverter. The z-source inverter employs a unique impedance network coupled with inverter and rectifier. It overcomes the conceptual barriers and limitations of the traditional voltage-source inverter such as V-source inverter and current-source inverter such as I-source inverter. By controlling the shoot-through duty cycle, the z-source inverter system provides ride-through capability Simulation results are presented to demonstrate the features. The result shows that the Z-source inverter is very promising for BLDC motor drive. For applications with a variable input voltage, this inverter is a very competitive topology.
