Patent ID: 11955953
Assignee: ROBERT BOSCH GMBH
Field: Basic communication processes (Electrical engineering)
Classification: CPC H | IPC H

Claim 9:
10. A method for controlling a semiconductor switch (3) comprising:
integrating (S1) a charging current into a capacitive component (11, 11a, 11b) to determine a quantity of charge (Q) in the capacitive component (11, 11a, 11b) from the integrated charging current, wherein the capacitive component is arranged between an input terminal (31) of the semiconductor switch (3) and an integrator (12, 12b);
comparing (S2) the determined quantity of charge (Q) in the capacitive component (11, 11a, 11b) with a preset limit value (S);
controlling (S3) the semiconductor switch (3) when the determined quantity of charge (Q) in the capacitive component (11, 11a, 11b) exceeds the preset limit value (S);
linking the result of a comparison device (13) and a control signal (D) with a logic gate (14); and
synchronizing the integration of the charging current with the control signal (D) for the semiconductor switch (3).
