基于三端口高频隔离变换器的混合型先进牵引供电设备及其控制策略

The advanced traction power supply equipment (ATPSE) based on power electronics technology presents an opportunity to address issues of negative-sequence power quality and neutral section simultaneously. However, existing power-frequency/high-frequency isolation schemes still face challenges such as low power density and high investment costs. To address these issues, a high-frequency isolated ATP...
