Three phase Two Stage Hysteresis Current Controlled Grid Connected Inverter System

Gayathri. S, Govada Lahari Chandana, Grace Rachel Selvaev .D


Design and implementation of a hysteresis current controlled grid-connected voltage source inverter (VSI) is presented. The proposed control technique retains the benefit of fast dynamic response, good reference tracking capability and simple implementation. Power from the renewable source is fed to the dc-dc boost converter to meet the grid required voltage level. Boosted voltage is connected to the inverter DC link. Power is fed to the 110V, 50Hz grid. Current injected to the grid is well within the IEEE 519 standard.
