Switching device for switched reluctance motor

[nothing909]

I have to choose four switching devices for a switched reluctance motor.

I have chosen a MOSFET, transistor and relay, what other device can be used?

How about a vacuum tube?

Are you sure you are understanding the requirements of your task correctly?

I just have to investigate four switching devices. What other switching device can I use?

What is wrong with a vacuum tube?
