The internal structure of IGBT as two BJT combined with a mosfet, so it still has the problem of body diode, isn't it?The body diode is an "artifact" of the mosfet manufacturing process, not something that can be removed. If you need something like a mosfet, without the body diode, maybe IGBT is what your looking for. Same driver as a mosfet is used with an IGBT.
But in that way of looking at an IGBT, isn't that "body diode" on the gate and not the collector and emitter? In the case of a mosfet the "body diode" is on the drain and source, in the path of the power flow through the device. Or at least that's how I understand it. Been wrong many times though.The internal structure of IGBT as two BJT combined with a mosfet, so it still has the problem of body diode, isn't it?
If the current not draw that much and still want to use IGBT then it's too expensive, if doesn't care about the price then using IGBT seems no problem for body diode, because the leader in the IGBT is bjt not the mosfet ...But in that way of looking at an IGBT, isn't that "body diode" on the gate and not the collector and emitter?

IGBT's and mosfets in the same "package", are not that different in price.If the current not draw that much and still want to use IGBT then it's too expensive, if doesn't care about the price then using IGBT seems no problem for body diode, because the leader in the IGBT is bjt not the mosfet ...
The source of circuit.
What I mean is two components, the one is mosfet and another is IGBT, and the price of IGBT is more expensive.IGBT's and mosfets in the same "package", are not that different in price.
Thats what I meant too. When I said "package" I didn't mean two devices in one "package". I meant the type of "package", like "D-Pac", "TO-220", etc. Is price really that different, when doing a one off? Maybe for a commercial product, but not for a personal use thing.What I mean is two components, the one is mosfet and another is IGBT, and the price of IGBT is more expensive.
