The current source inverter-fed induction motor drive (hereafter referred to as CSIM drive) is one of the widely used drives in the industry. Of the many strategies employed for the control of CSIM drive, angle control is the simplest scheme to incorporate the aspect of "frequency compensation," thus paving the way for a fast response CSIM drive. A step-by-step design of the angle-controlled CSIM drive is described. A systematic design of inner current loop, slip speed loop, outer speed loop,

... d frequency compensation loop is given. The design incorporates a linear relationship between the refer-ence input and output of electromagnetic torque and a strategy to obtain maximum torque per ampere. The commutation delay in the current source inverter is taken care of in the design of the frequency compensator. Experimental results are given in support of the design procedure. Abstract-As industry looks harder at energy conservation, more users of process steam are rediscovering the benefits of induction
