Switch and method for transferring signal voltage within a driver of a voltage semiconductor

摘要

The switch has a signal input (14a) that is arranged on a reference potential (P-1) and has a primary side (8a) of a driver (6) for a signal voltage (U-S1). A power source (16) is arranged on the primary side for generating current correlated with the signal voltage. A signal output (14b) is arranged on a secondary side (8b) for another signal voltage (U-S2). An independent claim is included for a method for signal voltage transmission within a driver of a power semiconductor switch.
