This invention discloses a method and system for planning and controlling the power-optimal current curve of a DC-DC converter. The method includes the following steps: obtaining power system parameters and task objectives; based on the power system parameters, controlling the load coil current within a given time period. T The value increases from 0 to the target value. I The current rise phase, and from I The current decrease phase, from zero to zero, is divided into multiple sub-phases, and the power value for each sub-phase is planned. Based on the power value of each sub-phase, the current curve for each sub-phase is recursively generated based on the differential relationship between power and current, thus forming the current curves for the current rise and current fall phases. The current curves for the current rise and current fall phases are output to a DC-DC converter to achieve closed-loop control of the load current. This invention can reduce instantaneous power demand and optimize power distribution, thereby reducing the requirements for power system capacity and improving system economy and reliability.
