Abstract

PURPOSE:To control closing angles responding to the number of revolution by alternately triggering flip-flop by two (2) edge signals having different phases, which are controlled by the member of revolution. CONSTITUTION:Circuits SW1, TRG1, SW2 and TRG2 are two edge signal generation circuits. F/V circuit delays the phases of edge signals for SW2 and T1 during high revolution speed. Two edge signals triger the flip-flop and control SW3 by the output. The phase difference between two edge signals produces a current through angle. Therefore, as excessive current does not flow during low revolution speed, the current through angle is shortened. As the revolution rate increases, the current through angle is made longer, thereby preventing the primary current from dropping.
