Research on the driving effects of new energy power generation side transformer infrastructure

This study aims to explore the intrinsic linkage mechanisms between the power transformer industry and the electric vehicle (EV) charging infrastructure sector. Utilizing industrial symbiosis theory as an analytical framework, this paper systematically dissects the symbiotic relationship formed by these two domains at both the physical exchange (electrical energy conversion) and information collaboration levels. It then empirically investigates the bidirectional driving effects arising from this relationship. The findings indicate that power transformers occupy a dual industrial ecological niche within the charging ecosystem, serving as both a "macro distribution hub" and a "micro power core," thereby constituting the technical foundation of the symbiotic relationship. The explosive growth of the charging infrastructure market has significantly stimulated the capacity expansion and technological upgrading of the traditional transformer industry through a "demand pull" effect. Concurrently, technological advancements in the transformer industry. The emergence of wide-bandgap semiconductor technology, represented by silicon carbide (SiC), is reshaping the form of this symbiotic relationship, signaling a future dynamic evolution towards higher levels of energy efficiency and system intelligence. This research uncovers the deep-seated logic of co-evolution between traditional power equipment and emerging infrastructure, offering theoretical insights for relevant industrial policy formulation and corporate strategic decision-making.
