The invention provides a power supply topology, a motor driving controller and a vehicle. A power supply topology in the motor driving controller comprises a first flyback power supply and a first forward power supply. The first flyback power supply is used for converting first direct current output by the first battery module into second direct current to supply power to the lower bridge arm driving circuit. And the first forward power supply is used for converting the second direct current into third direct current to supply power to the upper bridge arm driving circuit. According to the motor driving controller provided by the invention, the power supply topology adopts a two-stage power supply framework, and the motor driving controller can be powered by only one flyback power supply and one forward power supply, so that the volume of a transformer can be saved, the size of a single board can be reduced, and the space of the whole vehicle can be saved.

    本申请提供了一种电源拓扑、电机驱动控制器及车辆。电机驱动控制器中电源拓扑包括第一反激电源和第一正激电源。第一反激电源用于将第一电池模块输出的第一直流电转换为第二直流电为下桥臂驱动电路供电。第一正激电源用于将第二直流电转换为第三直流电为上桥臂驱动电路供电。本申请提供的电机驱动控制器中电源拓扑采用两级电源架构,仅通过一个反激电源和一个正激电源即可为电机驱动控制器供电,因而可以节省变压器的体积,减小单板尺寸,节省整车空间。
