Abstract :
This paper presents the Z - source inverter for adjustable speed drive system. The Z - source inverter employs a unique impedance network couple with inverter main circuit. By controlling the shoot through duty cycle, the Z - source inverter system using MOSFETS provide ride - through capability during voltage sags, reduces line harmonics, improves power factor and high reliability, and extends output voltage range. Analysis and simulation results will be presented to demonstrate new features. It reduces harmonics, electromagnetic interference.
