Application of TRIZ Theory in Power Electronic Circuits

TRIZ theory of invention, as a theory of invention and innovation, has been widely used in various fields. In this paper, the contradiction matrix of TRIZ theory is combined with power electronic topologies to systematically illustrate the construction laws and methods of new topologies. Taking the power electron conversion topology of DC-DC circuit as an example, the construction principles of several common topologies are analyzed, and the feasibility of the construction method is verified. In addition, combined with TRIZ theory to guide the regularity of the new topology of power electronics, a new type of soft switching high-gain enhanced converter is proposed, which provides a new idea for the construction of power electronic circuits with better performance.
