Microprocessor programming algorithms in electrical inverter drive systems are essential in developing and formulating modern methods in closed control circuits. The microprocessor used in the current research, TMS320f28335, has a high system clock s frequency (150 MHz) that reaches up to, which gives an almost perfect ability to output the three-voltage sinewave generated from the inverter under consideration. Obtaining a sinewave voltage means the lowest possible harmonics (THD) and thus the best performance of the induction motor at starting and dynamic stability. The current research used the directional inclusion method to implement the six inverter switches (IGBTs) mechanism. Mathematical calculations were made for Space Vector Pulse Width Modulation (SVPWM) method, and then the microprocessor was programmed to implement it. The practical board Voltage Source inverter (VSI) was tested extensively.
