Drivers for paralleled semiconductor switches
Patent
·
OSTI ID:1892779
An apparatus includes a plurality of parallel-connected semiconductor switches (e.g., silicon carbide (SiC) metal oxide semiconductor field effect transistors (MOSFETs) or other wide-bandgap semiconductor switches) and a plurality of driver circuits having outputs configured to be coupled to control terminals of respective ones of the plurality of semiconductor switches and configured to drive the parallel-connected semiconductor switches responsive to a common switch state control signal. The driver circuits may have respective different power supplies, which may be adjustable. Respective output resistors may couple respective ones of the driver circuits to respective ones of the semiconductor switches. The output resistors may be adjustable.
