Abstract:
In power electronic field, the level shifter gate driver IC suffers heavily from the negative voltage especially at the high side reference pin, which is normally connected with the load. Three half bridge level shifter gate driver ICs are tested under static and transient negative voltage condition. This paper will show the test method and point out the performance of each gate driver IC under the negative voltage condition.
