Static discharge system

摘要

A semiconductor circuit includes a three-terminal high voltage semiconductor device, a charge distribution structure and a static discharge system. The charge distribution structure has a plurality of conductors with a floating potential. The charge distribution structure is capacitively coupled to a first terminal of the semiconductor device. The static discharge system removes charge that accumulates on at least a subset of the conductors. The static discharge system removes the charge that accumulates on the subset of conductors when the semiconductor device is in a first state while allowing charge to accumulate on the subset of conductors when the semiconductor device is in a second state.
