  • SOFT START FOR BUCK CONVERTERS
    Publication number: 20230327550
    Abstract: A method of DC-DC power conversion includes converting a DC link voltage to a DC output voltage for a load that is lower than the DC link voltage using a buck converter. The method includes controlling the buck converter in a normal switching mode in response to the DC link voltage being below a predetermined high threshold. The method also includes controlling the buck converter in a soft start switching mode in response to the DC link voltage being at or above the predetermined high threshold.
