1500A-7V-phase thyristor power regulator circuit a plating It consists of the main circuit, control circuit and the protection circuit has three major components. The control c
ircuit includes a trigger circuit, synchronous power supply and other components. Given voltage Ug superimposed (given by the RP4) and synchronous voltage control transistor trigger circuit board VT5 work like state. When the circuit is overloaded (set value set by the potentiometer RP3, under normal circumstances, the regulator VS3 no breakdown), VS3 hit wear, VT2 conduction, VTi off, VT3, VT4 off thyristors closed, cutting off the main circuit, reaches overcurrent protection purposes.
