An Novel Hysteresis Current Control Technique (HCCT) for Single Phase VSI

Several HCCT and modified HCCT (MHCCT) are implemented for Single Phase VSI (SPVSI). This paper suggests an novel HCCT for the same converter which provides the benefit of both unipolar and bipolar switching technique. This novel HCCT reduces switching loss, eliminates the EMI effect by reducing the higher order harmonics and further more diminishes the Sub and Inter Harmonics (SIH) of the load current. Authors also compared results of the proposed control technique with some of existing HCCT. The simulation results, harmonic analysis of the load current of the novel control technique and other existing techniques are proposed and compared in the article. Hardware result of load current with the novel control technique is projected and also matched with simulation results for a motor Load.
