description The invention discloses a current acquisition circuit suitable for a space electric propulsion power supply system. The circuit comprises a sampling branch circuit, a first voltage clamping branch circuit and a conditioning branch circuit which are connected in parallel. The sampling branch circuit comprises a Hall sensor and a first resistor, wherein a preset sampling current range of the Hall sensor is set to be within 10mA, and the Hall sensor is used for collecting the current of the sampling branch circuit in real time; the first resistor is connected with the Hall sensor in series and used for eliminating device oscillation of the Hall sensor; the first voltage clamping branch comprises a plurality of series voltage stabilizing diodes and is used for carrying out voltage clamping andcurrent shunting on the acquisition circuit when the current exceeds the preset sampling current range in the starting stage of the space electric propulsion power supply system; and the conditioningbranch circuit is used fo
