SCL–ZSI for interline DVR
L. Jayaprakash
Abstract :
The Interline dynamic voltage restorer (DVR) is a custom power device has been proposed to mitigate voltage sags thereby protecting sensitive loads. A technique based on Embedded switched–inductor Z–source inverters have become a research hotspot because of their single–stage buck–boost inversion ability, and better immunity to EMI noises. However, their boost gains are limited because of higher component–voltage stresses and poor output power quality .To overcome these drawbacks, a new highvoltage boost impedance–source inverter called a switched–coupled–inductor quasi–Z–source inverter (SCL–qZSI) is proposed. The proposed inverter employs a unique impedance network couple with inverter main circuit and rectifier. By controlling the shoot through duty cycle, the proposed inverter system provide ride through capability during voltage sags and swells, reduces line harmonics, and improves power factor and high reliability. This paper presents the simulation results of switched–inductor Z–source inverter.
