Description

technical field [0001] The invention relates to the technical field of circuit optimization, in particular to a brainstorming algorithm-based power electronic circuit optimization method and its application. Background technique [0002] Power electronic circuits can effectively control power transmission by adjusting the supply current or voltage to adapt to the user's load, and have been widely used in various daily devices, such as mobile devices, computers, televisions, and uninterruptible power supplies. With the advancement of semiconductor technology and electronic packaging technology, the demand for automatic generation of power electronic circuits is getting higher and higher. [0003] The methods of automatic circuit design and optimization are mainly divided into two types: deterministic algorithm and stochastic algorithm. Deterministic algorithms, such as gradient methods and hill-climbing methods, tend to fall into local optima, resulting in suboptimal compone...
