The IGBT has nearly zero "on" resistance, which makes it ideal for switching applications, plus the input impedance is very high, so driving power is minimal.I know that IGBT is combine together with MOSFET and BJT. the common feature is a gate, a collector and a n emitter..
so what is the main different between IGBT vs (MOSFET & BJT)
I'm just going to add on to this. I was going to mention it this morning but I was in a rush to get to work, and didn't have enough time.The IGBT has nearly zero "on" resistance, which makes it ideal for switching applications, plus the input impedance is very high, so driving power is minimal.
Yes, at lower power levels MOSFETs are definitely superior. They are faster and smaller. IGBTs are generally used for large motor drivers, which can see very high currents.At lower voltages where the diode drop is a significant part of the operating voltage isn't the FET generally superior though?
I'm working on a project for harvesting and bucking up power from a 12V solar panel right now and keeping diode drops out of the current path is a concern on the input voltage side. I've looked at a lot of solar designs doing research and I don't recall seeing any IGBTs at all.
