Sliding Mode Controlled IDBHCC for Single phase LC filter PWM Inverter

Abstract

This paper describes a detailed model of nonlinear current control techniques. It mainly concentrates on Double Band Hysteresis Current controller (DBHCC) and an improved version of it called IDBHCC for one phase Grid Connected Voltage Source Inverter (GCVSI).LC filter has been used in the inverter to eliminate grid current error. In Combination with DBHCC and IDBHCC, Sliding Mode Control (SMC) has been used to generate inverter pulses. The results are verified through MATLAB simulation.
