The introduction of electronic transformer brings a new problem to the test of the primary and secondary integrated intelligent switch. This paper presents a method to increase the access function of the integrated access device, which can simultaneously access multi-mode intelligent switches with mixed large and small signals of various transformers. The influence on the voltage and current measurement accuracy can be ignored. At the same time, it uses the method of multi-channel synchronous sampling, and the large-signal and small-signal synchronous acquisition is carried out on the primary side and the secondary side. The detection of the multi-modal integrated intelligent switch is realized.
