给定节点数纯开关拓扑的拓扑推演

本文建立了一种以图论为基础的寻找新电路的拓扑推演方法，通过对开关状态的穷举和组合形成拓扑，并根据电路判据和可控性判据来判定拓扑的有效性。该方法具有系统化、机器化的特点，可以广泛的用于寻找软开关、功率因数校正等新型电力电子电路，还可以用于开关电容网络的研究。

Topological Deduction of Switch Circuits with Given Number of Vertex

An approach to searching for new circuit by topological deduction based on graph theory is established in the paper. Topologies are formed through enumerating and combining switching states. Circuit criteria and control criteria are introduced to determine the effectiveness of both states and topologies. The approach is systematic and automatic, which may be widely used in searching for new power electronic circuits such as soft switching circuits, power correction circuits, and also can be used in researching the switch capacitor networks.
