Control system for a mains frequency clocked supply unit of an intermediate voltage converter circuit

The system has a input voltage (uzk) measured (22) and fed to two low pass filter circuits (28,30) having different time constants. These provide voltage inputs to a differencing circuit (32). If the difference signal exceeds a predetermined threshold as determined by a processor (24) then a blockin...

Zusammenfassung:	The system has a input voltage (uzk) measured (22) and fed to two low pass filter circuits (28,30) having different time constants. These provide voltage inputs to a differencing circuit (32). If the difference signal exceeds a predetermined threshold as determined by a processor (24) then a blocking signal is generated (34).
