hi everyone.......
i am doing a project on stAR DELTA SWITCHING AT 300HZ in an alternator 14.5V 90A alternator.....
1) i want a switch that could operate at 120A can i use mosfet or igbt?
2)how to measure frequency at 7(+-)0.5 V 0 to100A dc ?
im confused please guid me

maybe you could give us a little more background information. An example would be why you would want to do this, along with some of the major constraints.

 

Usually this is done by using contactors.

Any particullar reason for using semiconductor switches?
