The steps of process of generated PWM (Pulse Width Modulation) are implemented by using a microcontroller 89c51 and using Personal Computer (PC). In this paper, the unipolar modulation technique is presented to overcome many problems. The generated pulses are fed to six pulses at bridge inverter consist of six (MOSFET) transistors. The fundamental operation of PWM is depending upon mathematical relationships between the Voltage and the Frequency (V/F) constant value, this relationship gives low harmonics that takes place the modulation process.
