Abstract: In order to meet the power demand of low-voltage equipment of electric vehicles, a multi-output flyback auxiliary power supply for electric vehicles is designed based on the control chip UC3844. It mainly includes the design of the peripheral circuit of the control chip, the design of high-frequency transformer, the design of voltage feedback circuit and the design of buffer and absorption circuit, etc. The validity and reliability of the designed circuit are verified by experiments. The experimental results show that the designed power supply has the advantages of small size, stable output voltage and high precision, which can meet the design requirements of auxiliary power supply.
Keywords: auxiliary power supply; UC3844; transformer
