摘要：The invention relates to a method for operating a power output stage (), inparticular an electrical machine, which comprises a bridge circuit () with at least one half-bridge (), wherein the half-bridge () has two power semiconductor switches () which are
connected in series and which are each supplied with an operating control voltage duringnormal operation in order to set a power voltage, and wherein the power voltage (u4, u5)of the respective power semiconductor switch () is detected for the purpose of short-circuit monitoring. In this case, provision is made, in order to check the functioning of theshort-circuit monitoring means in a check mode for the power semiconductor switches (),for a test control voltage which is below the operating control voltage to be set at leasttemporarily at the same time.
