A Design of an optoelectronic isolation device to protect the measurement system of the underwater discharge acoustic source

摘要：

　　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 bipolar 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.
