An AC current regulator comprises a source of AC voltage, load, an adjusting device, which includes transistor, diodes and varistor. The adjusting device comprises transistor of the opposite conductivity. Emitters of transistors are united one with another and with one of input terminals of the adjusting device. Collectors of transistors by means of diode are connected with a load, the second lead of which is connected with the second input terminal of the adjusting device. Bases of transistors are united one with another and through resistor with a movable contact of varistor, terminals of which are connected with input terminals of the adjusting device. |
