Voltage fluctuation processing method and device of DC/DC converter, medium and terminal

The invention provides a voltage fluctuation processing method of a DC/DC converter. The method comprises the following steps: initializing a load current observer based on a discrete tracking differentiator; monitoring the load current of the DC/DC converter through the load current observer to obtain a load current observation value; and acquiring a compensation current according to the load current observation value, and taking the compensation current as a feed-forward current in a feed-forward control system of the DC/DC converter. According to the method, the fluctuation of the bus voltage under the load disturbance condition is reduced to the minimum to the maximum extent, so that the phenomenon of bus voltage drop or soaring caused by sudden load change or fast load change is effectively inhibited, and the stability of system operation is greatly improved. 本发明提供一种DC/DC变换器的电压波动处理方法，包括：初始化基于离散跟踪微分器的负载电流观测器；通过所述负载电流观测器监测所述DC/DC变换器的负载电流，得到负载电流观测值；根据所述负载电流观测值获取补偿电流，以所述补偿电流作为所述DC/DC变换器的前馈控制系统中的前馈电流。本发明最大限度地
