| Abstract: | This paper puts forward a switching mode power supply scheme that applies to brushless direct current motor controlling module in the electric motor.The scheme is based on the high performance PWM integrated chip of electric current mode.The design adopts single-end flyback structure and gets 48V direct current power supply and 12V direct current output from the battery of electric motor car.It can well satisfy the power supply demand for the controlling module of the direct current motor in electric motor because it has some important advantages,such as quick response,excellent stability and precise voltage output.The paper provides the thought about designing the switch power as well as analyses and discusses on technological details. |
