FIELD: electrical engineering; electrical processing installations. ^ SUBSTANCE: with fully closed thyristors of bridge 2 loads 1 consume minimal power from supply mains. With fully open thyristors of bridge 2 input power of loads is maximal and higher than former one by 33.3%. In the process reactive power consumed from supply mains greatly reduces within this range. Minimal higher harmonics are passed to supply mains. Thyristors of bridge 2 are placed at potential twice as rarely as those of prior-art installations. ^ EFFECT: enhanced reliability of electrical installation. ^ 1 cl, 2 dwg |
