IGBTs are still used frequently in power electronics. Not sure what this person is going on about. They are cheap off the shelf components that are very durable and robust… Except when they are not, but that’s usually because of bad engineering around it.
Insulated Gate Bipolar Transistor. It’s essentially a cheaper way to handle high voltages.
Previous technology was commodity only up to around 200V.
