In order to drive trawl winch, a thyristor leonard control system or a commutatorless motor system has been used. However, a current source inverter-squirrel-cage induction motor drive system will be used to drive trawl winch because of its full four-quadrant regenerative capability, fuseless short-circuit proof capability and overall ruggedness. In this paper, the current source inverter-induction motor system for trawl winch is designed and tested. A vector control algorithm which is described by a assembly language is run by the microprocessor V20 (NEC). A DC machine driven by a chopper is used to simulate the speed-torque characteristics of the trawlnet. The armature current with some patterns is controlled by the chopper, so that the load torque of the induction motor is controlled also. The experimental results are shown to demonstrate the satisfactory speed control for the sine-wave change of load torque.
