6 Principles of IGBT photovoltaic inverter

As can be seen in the table, a standard-speed IGBT has the lowest VCEON, but the slowest fall time compared to the other two fast and ultrafast planar IGBTs. The fourth IGBT is a trench-gate IGBT optimized to deliver low con-duction and switching losses for high-frequency switching such as in solar inverter applications.
