switching device for on off control in AC circuits

Hi, i'm a beginner to power electronics. I'm doing a project in which I need a semiconductor switching device that provides on-off control using positive or negative pulse respectively for switching AC circuit. Please tell me which device I should use (SCR, GTO, Transistor, etc) and also its model no. Thanks in advance

I would use back to back mosfets for switching THE AC power.
You could drive them via a pulse trafo, or a gate driver supplied from an isolated high side supply.

thank u @teez, gate driver might my requirement. But can u provide me any circuit or any link where i can learn more about it?

driving gates of fets.....search for a tital in google like "high speed mosfet drive" , and the author is Laszlo Balogh.
That will give you good ides on gate drive
