Abstract
One of the inexpensive notions in present day power electronics control equipment is the objective of random pulse width modulation (RPWM) for control of semiconductor based power converters, accelerated by the progressively increasing anxiety with or regulations regarding electromagnetic fields, vibrations produced due to magnetic field and the induction of acoustic noise. The disperse or spread of acoustic noise spectra is obtained on induction motor by a differentcosimulation of RPWM generation for three phase inverter drive. This pattern is randomized by selecting the triangle randomly among the two triangles. The 8-bit linear shift register is used as feedback for arbitration selection. To generate the pulses sine reference wave is compared with east bit of the register output decide the winning triangle. The outcomes of cosimulation are presented for both RPWM and SPWM and compared Fundamental, Harmonic Spread Factor, Total Harmonic Distortion for various modulation index. Furthermore, Xilinx XC3S500E FPGA processor synthesis results are provided. The experimental validation of SPWM and RPWM are presented at the end and compared.
