METHOD AND CONTROL UNIT FOR PULSE-WIDTH-MODULATED CONTROL OF SWITCHING ELEMENTS IN A PULSE-CONTROLLED INVERTER

摘要

The invention relates to a method for pulse-width-modulated control of switching elements (4A-4F) in a pulse-controlled inverter (1), wherein, in a first control mode, the pulses in successive signal periods of the control signal each have a standard start or end time within the signal period or are arranged constantly centred in the centre of the signal period, and, in a second control mode, the pulses in successive signal periods of the control signal are alternately arranged once at the start of the signal period and once at the end of the signal period.
