I am constructing a square pulse generator capable of giving 5ms-100ms duration pulse at 300V DC. Current requirements are low (around few mA). Pulse duration is selected by a thumbwheel switch.
I used AT89S51 to generate 5ms-100ms duration pulses.
I have a 300 V DC power supply.
As the pulses are short duration relays can not be used. What is a suitable way of switching this 300 volts using control signal from microcontroller 89s51.
Any suggestion or link will be appreciated.
Thanks in advance.
