Abstract

PURPOSE:To perform phase control so that current may be balanced automatically with a composition of a low cost, by compensating a first and a second thyristor bridges for ignition angles on the leading side (or the lagging side) on one side and on the lagging side (or the leading side) on the other side. CONSTITUTION:When the output current Id1 of a thyristor bridge(TB) 3 is increased, and the output current Id2 of a TB 4 is reduced, and the unbalance of current is generated, then the secondary current of three-phase current transformers 7, 8 is also immediately changed, and the input of the unbalance detection signal V 1 of an unbalance detection circuit 9 to a balance controlling circuit 12 is provided. By the balance controlling circuit 12, the signal is added to input Valpha on one side, and against the TB 3, phase angle command signal Valpha1 is reduced to Valpha Valpha-V 1, and an ignition angle alpha1 is set in the lagging direction. For the TB 4, phase angle command signal Valpha2 is increased to Valpha Valpha+V 1, and an ignition angle alpha2 is set in the leading direction. Accordingly, output voltage Vd1 is lowered, and Vd2 is to be heightened. In other words, feedback control is performed so that the output current Id1 of the TB 3 may be reduced and the output current Id2 of the TB 4 may be increased.
