APPLICATIONS OF BIONICS IN DESIGN OF POWER ELECTRONICS SYSTEM

Abstract

Based on the reliability mechanism of biological system, the design theories and methods of high reliabe power electronic system, includingautonomous decentralized control,redundancy design, intelligent design, self-reproducion and self-repair, self-adaptive and self-organization control, are firstly described in detail. The research results show that the reliabi1ity of complex power electronic systems is improved markedly in these bionic methods. The power electronics technology can draw some research inspiration from living being. And bionics will have wide applications in the field of power electronics. As a concept Autonomous Cell (AC) and Autonomous Decentralized Power Electric System (ADPES) are defined. It is pointed that AC is autonomous controllable and autonomous cooperative. Based on AC, ADPES is built.A novel autonomous decentralized single-phase inverter of high reliability is inverstigated in the method of bionic. Bionic design methods of power electronics system are original from methodological point of view in this paper. Theresearch in this paper is a practical guide to the applications of bionics on power electronics, especial on design of high reliable power electronics systems.
