Hi friends,
I am sending you a schematic , I can drive a series rlc circuit directly with a microcontroller.However I need more current to drive it.I can not design a switching circuit or driver for it.I use a power n cahnnel mosfet but system is not working!Can you command on why it is not working.All I know is if gate-source voltage is greater than threshold voltage then drain-source will be short circuit or in other words mosfet will act as a switch and allow current flow from darain to source.But it is not working why?
Thanks.
