Abstract

The invention discloses a transient characteristic validation device for a DC-related circuit. The device comprises a master control unit, a signal processing unit, a power amplification unit, and anacquisition unit, wherein the acquisition unit is used to acquire signals output by the power amplification unit to obtain a signal waveform of the output signals, and is also used to compare the acquired signal waveform, which is output by the power amplification unit, with a transient waveform stored in the master control unit to obtain a validation result. The device disclosed by the inventionhas the characteristics that advantages and disadvantages of a linear power amplifier and a switching power amplifier are fully considered, independent output ports are designed according to differentrequirements of actual output current amplitudes and frequencies, and automatic adjustments can be carried out according to actual onsite demands; and the device is small in size and light in weight,and can be simply maintained and conveniently operated, so as to be highly applicable to a transient characteristic validation test of DC measuring equipment on an installation and operation site.
