The invention provides a ripple suppression method, device and terminal of a converter and a readable storage medium. The method comprises the steps of acquiring a DC-side power grid parameter and anAC-side power grid parameter of the converter; obtaining a ripple power grid parameter according to the DC-side power grid parameter and the AC-side power grid parameter; calculating a compensation voltage of a DC side of the converter according to the ripple power grid parameter; acquiring a modulation voltage of the converter; obtaining a control voltage of the converter according to the compensation voltage and the modulation voltage; and controlling the converter according to the control voltage. By acquiring the DC-side power grid parameter and the AC-side power grid parameter of the converter, the DC-side power grid parameter and the AC-side power grid parameter are processed to obtain the DC-side compensation voltage, the compensation voltage is superposed to the modulation voltageof the converter to obtain the control voltage, and the converter is controlled according to the control voltage; and by the ripple suppression method, DC-side ripple filtering equipment is not neededto be additionally arranged, and the hardware investment cost is reduced.
