This article represents an inclusive study of the current source inverter (CSI)-fed induction motor drives. It also reviews various control methods, selective harmonic elimination techniques and methods for decrease in switching losses in CSI fed IM drives. Power electronics has changed hastily through the last few decades and the number of applications has been increasing, mainly due to the developments of the semiconductor devices and the microprocessor technology. A dc-link current-source is provided by a Buck chopper. The amplitude and frequency of current-source inverter's output is controlled by asynchronous PWM-CSI method. Between the input terminal of induction motor and the current-source inverter a bank of capacitors is used to eliminate the high order harmonic currents, suppress the spike voltages across the IGBT switches and make guarantee the continuity of motor's current.
