An adaptive gate drive for an inverter includes control circuitry having a Field Programmable Gate Array (FPGA) and includes power circuitry having a plurality of FETs for operating a switching device, such as a Trench Gate Insulated Gate Bipolar Transistor (IGBT device). The control circuitry provides switching signals for operating the switching device. In addition, the control circuitry receives signals of output current of the IGBT device, temperature of the IGBT device, and DC link voltage. The FPGA has a plurality of operating points stored therein. Each operating point has corresponding parameters for a control signal that is used to control the turn-on or turn- off behavior of the IGBT device. During operation, the control circuitry compares the measured current, voltage and temperature operating points stored in the FPGA and sends the corresponding parameters to the gate drive circuit. The gate drive modifies the signal on the gate of the IGBT accordingly and thereby optimizes the turn-on and/or turn-off behavior of the device based on actual operating conditions.

L'invention concerne une commande de grille adaptative destinée à un inverseur, qui comprend des circuits de commande à prédiffusé programmable (FPGA) ainsi que des circuits d'alimentation à plusieurs TEC destinés à mettre en oeuvre un dispositif de commutation, notamment un transistor bipolaire à grille isolée et en tranchée (dispositif IGBT). Les circuits de commande produisent des signaux de commutation destinés à commander le dispositif de commutation. En outre, les circuits de commande reçoivent des signaux du courant de sortie du dispositif IGBT, la température de ce dispositif IGBT, et une tension de liaison CC. Le FPGA contient plusieurs points de commande stockés. Chaque point de commande possède des paramètres correspondants destinés à un signal de commande qui est utilisé pour commander le comportement marche et/ou arrêt du dispositif IGBT. En fonctionnement, les circuits de commande comparent le courant mesuré, les points de commande de tension et de température stockés dans le FPGA et envoient les paramètres correspondants au circuit de commande de grille. La commande de grille modifie le signal sur la grille de l'IGBT en conséquence et optimise ainsi le comportement marche et/ou arrêt du dispositif sur la base de conditions de commande réelles.
