Abstract

This paper discusses the means of electrical isolation especially the characteristics of photoelectric isolation, magnetoelectric isolation and floating ground in common use. The two typical applications are presented based on applied requirement. One is analog testing module which consists of V/F conversion circuit and photoelectric isolation circuit. First analog signals are converted frequency signals and then frequency signals are transferred by photoelectric coupler. It is with low linearity error, high test precision and high isolated voltage. Another is digital signals test module based on isolated transformer. It uses the device which is quad-channel digital isolator with an intergraded isolated dc-to-dc converter. The device provides power supply to tested circuit. The module is small volume and high isolation voltage. Both applications are with practicability by validated with applied.
