Feedforward indirect vector control of a matrix converter-fed induction motor drive

Abstract

This paper describes the development of closed loop control techniques for matrix converter fed induction motor drives. A prototype drive rated at 2.5kW is wed to demonstrate closed loop speed control using vector control technique. Solutions to the special problems associated with the power circuit and implementation of closed loop control in the matrix converter drive are given. Experimental results demonstrating the control techniques are presented for both motoring and generating operations gi the matrix converter drive in transient and steady-state.
