    I am looking for some recommendations regarding an application I am working on. I have a 110 volt AC circuit. I need a 3 second ramp up to full power at power on, like a rheostat effect but without using a rheostat or timer. I also have a size constraint, where I would like to fit whatever component is used into no more than a ¾” square housing. Any help is appreciated.

    How many amps is the load? Is there reactance from the load? Check National Semiconductor's website reguarding IGBTs and Power Mosfets.
