  • Integrated on-board charger and auxiliary power module using a triple active bridge for electric vehicles
    Patent number: 12294294
    Abstract: A power conversion system including a triple active bridge (TAB) is provided. The system includes a power factor correction (PFC) module and a three port converter (TPC) module, with no post-regulation or additional stages required. The TPC module includes an OBC full-bridge and an APM full-bridge, each being inductively coupled to the output of the PFC full-bridge, thereby forming the TAB. The OBC full-bridge is adapted to convert an AC input into a high-voltage DC output for a high-voltage battery, and the APM full-bridge is adapted to convert an AC input into a low-voltage DC output for a low-voltage battery. The power conversion system can accept a single-phase AC input and a three-phase AC input, has a lower current stress as compared to prior art TPCs, and freely transfers power from among any ports.
