Range extending system for full-rotating-speed-domain inverter-free vehicle

The invention discloses a range extending system for a full-rotating-speed-domain inverter-free vehicle. The system comprises an engine, the engine is mechanically connected with a generator, the alternating current output end of the generator is connected with the input end of a rectifier, the output end of the rectifier is connected with the output end of a high-voltage battery pack in parallel, the high-voltage battery pack is connected with a pressurization module, and the pressurization module is connected with the motor controller. The three-phase rectifier is used for directly rectifying the alternating current generated by the generator, and the rectified current is directly used as an energy source of the motor controller and the high-voltage battery; by adding the pressurization module, the working range of the generator is wider, and the vehicle can generate power at a low rotating speed. 本发明公开了一种全转速域无逆变器车用增程系统，包括发动机，所述发动机机械连接发电机，所述发电机的交流电输出端连接整流器输入端，所述整流器输出端并联高压电池包的输出端，所述高压电池包连接增压模块，所述增压模块连接电机控制器。
