Hi, I'm developing a power generator that uses different power sources (most of them from renewable resources) to provide electricity, heat, etc. Right now I'm in need in some help because I need to be able to switch from 2 power supplies but I need to do the switching by software (using a Raspberry Pi). I've been told I could use Tip122 transistors, but I'm not sure the following circuit is possible since I've seen common uses of tip122 and all of them connect the emitter to ground. Is this circuit possible/safe? (RPi boxes just mean that tip122 bases will be controlled by RPi GPIO pins) Is it possible to use tip122 to do this kind of switching or should I use other components?
