A.C induction motor is the workhorse of industrial and residential motor applications due to its robustness, durability and reliability. Normally induction motors are constant speed motors but various application needs variable speed so speed control of induction motor is a big concern now a days. This paper presents the design and analysis of speed control of three phase induction motor using IGBT as switches in the three phase voltage source inverter with constant V/F method control in closed loop using dsPIC30F4011 controller.dsPIC30F4011 is a 16 bit high performance digital signal controller (DSC). DSC is a single chip embedded controller which has both the features of microcontroller and DSP.A 1HP, 3 Phase, 415 volt, 50Hz, 1405 RPM induction motor is used as load for the inverter. Digital storage oscilloscope is used to record and analyze the waveforms.
