The Appliance of Matlab in the Research of the
Environmentalistic Transducer
Abstract: Combining the appliance of transducer field, this paper introduces the electrocircuit simulation software, matlab, and its appliance traits and appliance scope .With the development of high power semi-conductor technology, especially,the appearance of IGBT , the research and production on transducer takes on a new look. Contraposing the development state of home and aboard’s Transducer and facing the problem that the exploitation and using sources affect environment protection heavily, it proposes Environmentalistic Transducer technical Scheme. A three-phase AC-DC-AC voltage-source Transducer was studied with theoretical analysis and digital simulation. Firstly, the basic principle and control law of a three-phase AC-DC-AC voltage-source Transducer gives to specify the parameters of a rectifier system with a closed voltage loop. Secondly, in detail, it addresses the technical scheme of the Appliance of Matlab in the Research of the Environmentalistic Transducer ,using simulink ,one of the tools in matlab, to establish structure model, through the control of dimensional vector SPWM to make simulation . Finally, this paper makes simulation research on it , then, shows some comparative results to validate the model it sets up.That is ,power factor comes up to one,the harmonic pollution to power net equal to zero.The outcome indicates the Research of the Environmentalistic Transducer is realizable and it will be glorious in the future.
