#CMT# #/CMT# Method for controlling a self-guided three-phase pulse rectifier system (1) comprises hysteresis switching parts (27, 28, 29) having prescribed gauges (55, 56, 57) of the switching hysteresis via control inputs (64, 65, 66). A hysteresis target unit (67) forms the gauges of the switching hystereses based on the phase current control deviations (39, 40, 41). The hysteresis target unit for each phase has the same structure. #CMT#USE : #/CMT# Method for controlling a self-guided three-phase pulse rectifier system. #CMT#ADVANTAGE : #/CMT# The same switching frequency and a coordination of the switching of the bridge branches within a pulse interval are achieved. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a block diagram of the three-phase pulse rectifier system. 1 : Three-phase pulse rectifier system 27, 28, 29 : Switching parts 39, 40, 41 : Phase current control deviations 55, 56, 57 : Gauges 64, 65, 66 : Control inputs 67 : Hysteresis target unit. |
