Simulation and control of induction motor operations by using a computer

Abstract EN

The principle operation of pulse width modulation (PWM) method is depending upon mathematical relationships between the voltage and the frequency to decrease the harmonics that take exists place due to the modulation process.

This mathematic relationship is calculated in the main program where the storage in personal computer (PC).

The control signal of PWM inverters is generated by comparing a reference sinusoidal wave and a triangular signal.
