Theowchartillustratesthechoiceofunit,basedontheratedsupplyvoltage,theneedtocontrolpulsetrans-
formerswithoneortwosecondarywindingsandthemaximumeldcurrentrequested.
Thereisnoneedtomakeadistinctionbetweentwoorfour-quadrantdrives;thisisdonebyconguringjumper
S1ontheFIRXP-XXpowercard.ON=4Q(default),OFF=2Q(seeFigure11.3.5).
ThecontrolunitiscapableofcontrollingSCRpowerbridgeswithfourpossiblecongurations,whichmustalso
betakenintoaccountwhenchoosingtheappropriateCUwiththerelativeconnectioncablesandpulsetrans-
formers.Thesefourpossiblecongurations,referringtotwo-quadrantbridges,areillustratedbelow(thesame
choicesapplytofour-quadrantbridges).Likewise,themainsvoltageandmax.eldcurrentarenotconsidered..
Configuration 1: Single bridge with 1 SCR per branch Configuration 2: 1 single bridge with 1 SCR per branch in parallel
