摘　　要：基于生物可靠性机理,系统地探讨了高可靠性电力电子系统的设计理论和方法,包括自律分散控制、冗余设计、自复制和自修复、智能化设计、自适应控制及自组织控制。利用这些仿生设计理论和方法,可提高电力电于系统的可靠性。提出了自律单元和自律分散电力电子系统等重要概念, 并指出:自律单元应具有自律可控性和自律协调性,自律分散的电力电子控制系统基于自律单元;自律分散控制系统代表了以后高可靠复杂功率变换器系统的一种极具前景的发展方向。最后,基于生物系统的自律分散控制思想,设计了一种新颖的单相逆变器。应用实例表明,仿生学在电力电子技术中,尤其在高可靠性电力电于系统设计中,有着广阔的应用前景。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.
