Sufficient voltage can be obtained from the inverter by over modulating, but this produces distortion of the output waveform -. In recent past, Third-Harmonic injection Pulse Width Modulation (THIPWM) switching technique is developed and widely used for three phase PWM inverter and the multilevel inverters .
dynamic behavior of the motor during operation.2.2 Three-Phase Voltage Source Inverter (VSI)The inverter is responsible for converting the constant D supply into a variable-frequency, variable-amplitude AC output that drives the induction motor. It consists of six I
Three phase bridge inverter are widely used for ac motor drives and general purpose ac supplies. Fig 1 shows the inverter circuit suppling a star connected load. The circuit consist of three half bridge , which are mutually phase shifted by 2π/3 angle to generate the three phase voltage waves. Fig 1: Circuit configuration of VSI.
erter: A three-phase voltage source inverter is modeled using power electronic switches (IGBTs). The inverter conve s the DC voltage into a controlled three-phase AC supply with variable frequency and amplitude.Induction Motor Model: A squirrel cage induction
