Abstract:

200 kW pulse width machine high end of the curtain gate voltage is as high as 27,000 volts,while the sampling voltage is only a few volts.In real-time sampling of the pressure on the high end of the curtain gate,it is necessary to protect the security of the transmitter and the sampling circuit,which requires that the sampling circuit have the characteristics of high pressure and anti-interference.

Key words: pulse width machine;resistant hypertension;interference
