description The invention relates to an automatic test system and method for output ripples of a power supply module, belongs to the technical field of power supplies, and solves the problems that in the prior art, the test efficiency of the output ripples of the power supply module is low, the cost is high, and the automatic test requirement of the output ripples of the multi-output power supply module cannot be met. The system comprises a ripple test module used for configuring a port switching instruction, a load adjustment instruction, a configuration instruction and a data acquisition instruction of each to-be-tested output end of a to-be-tested power supply module, a port expansion controller which is used for performing port switching according to the received port switching instruction so as to connect the to-be-tested output end of the corresponding to-be-tested power supply module with the input end of an oscilloscope, a program control electronic load which is used for configuring the load of each to-be-tested
