Abstract

A control switch for power semiconductors (50,52) in bridge topology comprises primary (20) and at least one secondary (30,32) sides joined by a signal transmitter (40,44) and DC/DC converter (42,46). The secondary side voltage is evaluated in case of error and/or status information, sent to the primary and different voltages given. An independent claim is also included for a process to transmit errors and/or status information in the above.
