Patent ID: 10454467

Abstract:
The present invention relates to a control device (1) for at least one transistor, referred to as the controlled transistor (3), comprising:—said controlled transistor (3) which comprises a control electrode (Ec) and two other electrodes (E1 and E2),—a main control circuit (5) connected to the control electrode (Ec) of the controlled transistor (3) and configured, according to a main mode of operation, to control the state of the controlled transistor (3) and,—an auxiliary control circuit (11) configured, according to an auxiliary mode of operation, to inject an auxiliary current opposing the current circulating between the main control circuit (5) and the control electrode (Ec) of the controlled transistor (3), characterized in that the control device (1) also comprises a control circuit (15) of the auxiliary control circuit (11), said control circuit (15) being configured to block or authorize the auxiliary operation of the auxiliary control circuit (11) depending on the commands from the main control circuit (5).
