Abstract: Research work carried out to investigate the effect of loads (combination of resistive, capacitive, and inductive) on the IGBT based power system. Total harmonic distortion in the input and output is calculated. Eight different combinations of the load are taken with different values of inductance keeping resistance and capacitance constant. Input and output voltages were recorded for all combinations using Gold wave software having duration of 1 sec with sampling rate of 16,000. A computer algorithm is designed to calculate total harmonic distortion in the input and output of the system. The designed microcontroller and IGBT based power system shows reduction in the distortion at the output.
