DEVICE FOR CONTROL OVER TRIAC Russian patent published in 1995 - IPC

FIELD: radio engineering. SUBSTANCE: remote polarity switch 8 and set switches which enable operation of device to be set under different modes of commutation are inserted into circuit of device to ensure commutation of triac under mode of single switching on in different half-waves of alternating current, under mode of formation of series of unipolar commutations and under mode of alternation of single switchings and of series of commutations in different polarities of half-waves of system voltage. EFFECT: expanded operational capabilities, improved efficiency of control. 2 dwg
