| description | A DC/DC convert output ripple control method and device are provided, After collecting the input voltage of DC/DC converter and obtaining the input voltage disturbance, The influence of the input voltage disturbance on the output signal (including the output voltage and the output current) is eliminated by acquiring a first output value in the voltage loop that eliminates the influence of the input voltage disturbance on the output voltage and acquiring a second output value in the current loop that eliminates the influence of the input voltage disturbance on the output current. On the premiseof not adding hardware, the influence of input voltage disturbance on output signal is eliminated, and the cost is reduced. Further, the smaller of the first output value and the second output valueis output to drive the on and off of the power device, so that the system works in the voltage loop when the load is small, and switches to the current loop when the load is increased to a certain degree, thereby improving the |
