The invention provides a constant-current power supply unit for an instantaneous high-power load, relates to a system composition and a principle of a novel constant-current power supply unit based on a super capacitor, belongs to the field of power supply system design, and aims to provide a general scheme for solving the problem of power supply of the instantaneous high-power load on a satellite platform. The power supply unit is mainly formed by connecting a constant-current charging module, a super capacitor module and a constant-current discharging module in series. Wherein the super capacitor module is used as an energy power container, the constant-current charging module is used for realizing isolation between a capacitor and a power bus and charging management, and the constant-current discharging module is used for realizing isolation between the capacitor and a load and discharging management. The three modules are integrated into a whole and are externally connected with a bus and a load power supply, and constant-current power supply for an instantaneous high-power load can be realized by utilizing four led-out control pins.
