Goal: I want to build a circuit that converts 700V DC supply to 700V pulses of 15ms duration.
From what I have learnt from online, is that Arduino controller can be used with Relay module to control such high voltage. But the voltage is limited to 250V AC or 20-30V DC.
Question: Is there any specific relay module that can control such high voltage (700) that can be controlled with Arduino. If not any other ideas are appreciated.
(Update on the question, adding details)
I am trying to do electroporation for zebra fish embryos. The details can be found here. For that i need two pulses of 0-700V of 15ms durationwhich will create 3500V/cm electric field. My lab has already bought Trek Model 2210 as DC source which will vary from 0-1000V. I have to design a pulse generator which will generate only two pulses of 15ms duration and 700V. More than two pulses will destroy the cells. My plan is to
Arduino----Buffer circuit---relay/power MOSFET (will be connected with 1000V source)---cell
When the Arduino will provide voltage to relay it will switch on and supply the voltage 0-1000V. How long it will stay on will be controlled by ARDUINO.
However, i am not getting any relay which can handle such high voltage. I am open to suggestions how i can solve the problem.
