  • Method of controlling an IGBT and a gate driver
    Patent number: 9154125
    Abstract: A method is disclosed for controlling an IGBT component and a gate driver. An exemplary method includes producing, with two separate driver circuits, a gate voltage for controlling the IGBT component, the outputs of the driver circuits being connected to free ends of a series connection of resistive components. A location, such as a midpoint between the series connection, forms the gate voltage.
    Type: Grant
