Abstract :
The authors present a systematic study of an induction motor drive system employing a load commutated current source inverter (LCCSI). The steady-state characteristics of a LCCSI-fed induction motor are shown to be the intermediate characteristics between the voltage source inverter (VSI) and the auto sequentially commutated current source inverter (ASCI). The dynamic characteristics of the LCCSI-fed induction motor are investigated using a linearised model. A study through the pole/zero locations of the linearized system shows that a V/Hz ratio control loop plays an essential role in the stabilization of the system
