Patent ID: 11916545
Assignee: SIEMENS AKTIENGESELLSCHAFT
Field: Basic communication processes (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 13:
14. A gate driver, comprising:
a measurement unit having an input operatively coupled to a drain terminal of a power semiconductor element and an output providing a test drain source voltage;
an adding unit having a first input operatively coupled to the measuring unit output for receiving the test drain source voltage, a second input operatively coupled to a reference gate voltage, and an output providing a switch on gate voltage formed by a total of the first and second inputs;
a first switch operatively coupled on one end to the output of the adding unit and on another end to a gate terminal of the power semiconductor element; and
a second switch operatively coupled on one end to the another end of the first switch and the gate terminal of the power semiconductor element and on another end to a switch off gate voltage;
wherein the gate driver applies the switch on gate voltage to the gate terminal of the power semiconductor element when the first switch is closed and the second switch is opened, and applies the switch off gate voltage to the gate terminal of the power semiconductor element when the first switch is opened and the second switch is closed.
