The invention provides a vehicle-mounted charger, a voltage stabilizer and an electric vehicle. The vehicle-mounted charger comprises a power circuit, a control circuit, a driving circuit, a power management circuit and a voltage stabilizer. The voltage stabilizer comprises a switching tube, a voltage stabilizing tube and a voltage division circuit. The first end of the switching tube is used for receiving first voltage. The control end of the switching tube is used for receiving second voltage from the power management circuit, and the second voltage is larger than the first voltage. By adopting the vehicle-mounted charger, the switching tube can work in the saturation region by increasing the voltage of the control end of the switching tube in the voltage stabilizer, when the voltage stabilizer outputs the target output voltage, the required first voltage value is reduced, the range of the first voltage is further expanded, the structure is simple, and the applicability is high.

    本申请提供了一种车载充电机、稳压器以及电动汽车。车载充电机包括功率电路、控制电路、驱动电路、电源管理电路和稳压器。稳压器包括开关管,稳压管和分压电路。开关管的第一端用于接收第一电压。开关管的控制端用于接收来自电源管理电路的第二电压,第二电压大于第一电压。采用本申请,车载充电机可以通过提高稳压器中开关管的控制端的电压使得开关管工作于饱和区,在稳压器输出目标输出电压时,降低所需的第一电压值,进而扩大第一电压的范围,结构简单,适用性强。
