Converter is a professional term in the field of chemical engineering, referring to a device used to achieve the conversion of substances or energy forms. It is included in the second edition of “Chemical Engineering Terms on Both Sides of the Taiwan Strait”. The definition and discipline classification of this term have been determined [1].
In industrial applications, power electronic systems based on power converters are widely used for the control and conversion of industrial and household electrical energy. Insulated Gate Bipolar Transistor (IGBT) serves as the core component, dominating the power converter market, with a market size of 6.6 billion US dollars in 2020. In terms of thermal management technology, the direct cooling structure reduces the thermal resistance by 30% compared to traditional solutions [4]. Industry analysis covers dimensions such as supply and demand balance, competitive landscape, and life cycle, and research methods include various methodologies such as system analysis, structural analysis, and case studies [2-3].
