METHOD FOR OPERATING A DRIVE CONTROL FACILITY AND DRIVE CONTROL FACILITY OPERATING ACCORDING TO SAID METHOD

摘要

A method is disclosed for the regenerative operation of a drive control facility, which includes an inverter with semiconductor switches controllable by control signals. A control logic for each control signal determines a control signal time instant and each of the semiconductor switches is controlled by a corresponding control signal generated by the control logic at the respective control signal time instant. Individual semiconductor switches are controlled prior to the determined control signal time instant by a corresponding control signal having a predetermined pre-ignition angle.
