Abstract
A drive control device having an inverter with semiconductor switches controlled by control signals is operated by calculating with a control logic a control signal time instant for each control signal, transmitting during operation the control signal time instants with the control logic during switching pauses of the semiconductor switches from a low-voltage side of the drive control device to a high-voltage side of the drive control device having the inverter, and generating the control signals for controlling the semiconductor switches on the high-voltage side based on the transmitted control signal time instants.
