The invention discloses a power supply ripple simulation system with a state monitoring function, and relates to the field of ripple voltage generation. The problems that in the prior art, the randomness of ripples cannot be simulated in the ripple voltage simulation process, the amplitude of the output ripple voltage is fixed, and the state of the output ripple voltage cannot be monitored in realtime are solved. An upper computer control unit is used for sending an instruction for controlling the waveform, the amplitude and the frequency of ripple waves to the ripple wave simulation and power supply state monitoring unit, and is also used for displaying a voltage value and a current value with ripple wave direct current output by the ripple wave simulation and power supply state monitoring unit; a DC power supply unit is used for providing a DC power supply for the ripple simulation and power supply state monitoring unit; and a ripple simulation and power supply state monitoring unitis used for generating direct current with ripples according to the received control instruction and the DC power supply signal, collecting a voltage value and a current value of the direct current with the ripples, and uploading the voltage value and the current value to the upper computer control unit. According to the invention, the direct current with ripples is provided.
Description
technical field [0001] The present invention relates to the field of ripple voltage generation. Background technique [0002] In the design reliability verification process of modern electronic systems, the ripple index of the power supply is an important test index, and it is usually necessary to test the anti-interference ability of the electronic system to the power supply ripple. This requires a power supply with interference signal components, which can provide a DC voltage with ripples. The amplitude of the provided DC voltage can be changed according to requirements, and the superimposed analog ripple needs to meet the power spectrum of the actual ripple. Distribution characteristics, amplitude and frequency can also be changed according to requirements, and achieve a certain accuracy under load conditions. [0003] In the prior art, special cases such as sine waves, triangular waves, and rectangular waves are usually used for the simulation of ripples, which cannot ...
