    Abstract :

    In this paper a novel technique is introduced for Cascaded Multilevel Inverter using Lookup Table Method for reduction of leakage current. The performance of the Hybrid Multicarrier Modulation using Lookup Table Method (HMCMLTM) and its effect on leakage current was analyzed with HMCM using Third Harmonic Injection (HMCMTHI) and HMCM (Without LTM and THI) in MATLAB/SIMULINK environment. It was inferred that the HMCMLTM possess lesser leakage current with higher fundamental voltage and lesser harmonics when compared with other existing techniques. The hardware setup is built for HMCMLTM and the inverter is operated by using microcontroller (ATMEGA328P-PU) controller which generates PWM pulses. The semiconductor switching device (MOSFET Driver IR2110) is used for the switching purpose to obtain the required output. And the hardware results are validated with the simulation results.
