Hi guys, I'm new here and a novice with arduino. Have some experience with electronics but the following is a HV project that I've been working on.
The project is a plasma spark ignition setup for a gasoline generator to be run on fuel and water vapor. The ignition system is basically a capacitive discharge ignition. The cap is charged with a solid state bedini circuit that charges the cap to 150-300 volt. A BT151 800V thyristor is used to dump the cap to the Plus side of the ignition coil. Up untill now the triggering of the BT151 was done mechanically with contact points but we would like to use a Hall sensor in the future.
Currently I have the system on the testbench and would like to trigger the thyristor with the PWM output of the arduino. I have tried to take a output and connect it to gate but that didn't work for long, I may have fried output 11. I would love to get some help to setup the arduino board and protect it from HV spikes . Could I just use diode like 1n4007 on the output in series to the gate of the thyristor??
Thanks for your help.
