To address the current issues in the construction and operation of electric vehicle charging stations

such as high distribution network losses

poor user experience

long construction cycles

and high installation costs

this study employs a 24-pulse phase-shifting transformer based on the extended-triangle phase-shifting principle. By integrating liquid-cooling

thermal-management

and efficiency-optimization technologies

a pre-installed integrated power distribution and EV charging system was developed. The proposed system effectively suppresses harmonic interference and minimizes distribution losses

thereby enhancing power conversion efficiency and service reliability. Furthermore

its modular design streamlines on-site installation

accelerates commissioning

and significantly reduces overall capital expenditure

demonstrating considerable potential for widespread adoption.
