The EUE-100130000 circuit has been designed to provide gate firing control pulses to firing circuits used in thyristor controlled power supplies.  The circuit may be configured to operate in 6-pulse, 6-pulse reversing, or 12-pulse power supply circuits. 

The output of the circuit is arranged in two groups, each group can be used for any 6 pulse power supply configuration.  In 12-pulse mode, Group 2 pulses lag Group 1 by 30 degrees.  Group 1 is used for the 'delta' circuit and Group 2 is used for the 'wye' circuit.  In 6-pulse mode, both output groups are in phase.
