FIELD: physics. ^ SUBSTANCE: frequency-pulse duration alternating voltage controller has an adder, an integrator, a relay element, comparators, dynamic D flip-flops, switch elements (thyristors), load resistors connected in a star circuit with a neutral terminal, a setting signal source and a three-phase voltage source. Said alternating current controller includes three dynamic D flip-flops, which enable to generate 'packets' of sinusoidal voltage across the load with a whole number of periods of mains voltage. ^ EFFECT: high energy efficiency. ^ 5 dwg |
