Paper Abstract

In this paper, an optoelectronic isolation device is designed to protect the measurement system of underwater discharge acoustic source (UDAS), from the harmful HV-GND drift. In this device, one linear optocoupler HCNR200 and four high speed operation amplifiers are used to perform a symmetric ‘electronic-optic-electronic’ conversion, and a method of setting a biased voltage is used to avoid the problem caused by the ‘bi-polar’ input signals. Verified by a pSpice simulation, this device can not only achieve a complete electric isolation of the HV system and the measurement system, but also realize a fine restore of the input signals.
