Assignee: MERITOR ELECTRIC VEHICLES GERMANY GMBH
Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC H  B  Y | IPC B  H

Claim 4:
5. A semiconductor circuit, comprising:
a plurality of semiconductors configured to form a power converter;
driver circuits operably connected to the plurality of semiconductors in one-to one correspondence;
a control unit;
a signal line arranged between the control unit and the plurality of semiconductors for transmitting data in accordance with a protocol for controlling the plurality of semiconductors and for additionally transmitting a sign-of-life signal,
wherein the driver circuits are designed to switch off the plurality of semiconductors, when the sign-of-life signal is absent;
wherein the plurality of semiconductors of the power converter are switched by optimized pulse patterns; and
wherein the control unit is arranged to switch off transmission of the sign-of-life signal for initiating a protective intervention.
