Are IGBTs suitable for high-voltage and high-current applications?

Despite the fact that IGBTs have been in the market for a while, this technology is still perfectly suited for high-voltage and high-current applications. The usage of IGBTs is growing not only in the classical applications, but also in new ones. This is due to the fact that new technologies are able to switch up to 100 kHz.

Why are IGBT devices designed for applications specifics?

Today IGBT designers have reached a very high understanding of the device physics and how to tune it. Hence most of the IGBT manufacturers design the devices for applications specifics. They are optimizing the trade-off curve in order to achieve the highest efficiency for a given applications.

Are insulated-gate bipolar transistors a good choice for solar inverter applications?

For solar inverter applications, it is well known that insulated-gate bipolar transistors (IGBTs) ofer benefits compared to other types of power devices, like high-current-carrying capability, gate control using voltage instead of current and the ability to match the co-pack diode with the IGBT.

Can an IGBT be connected to a power-MOSFET?

It is possible to associate an IGBT with a darlington configuration between a high-voltage PNP bipolar transistor and a power-MOSFET (see Figure 3). The idea behind this power device is to overcome the difficulty in increasing the power MOSFET current handling capability.
