Abstract

PURPOSE: To prevent a current from intermittently flowing when a firing start is delayed by one cycle and a thyristor from generating reverse voltage by providing always the firing time relationship of a pair of AC converters in commutation phase difference of 30°.
CONSTITUTION: A monostable multivibrator (MM) 14 is set in advance at predetermined time T to generate a BPP signal after the time limit from the generation of the output signal from an AND gate 12 to the gate of a thyristor. Assuming that the setting times of the mono-malti MM 14 of the starter controllers US1, US2 at AC-DC converters CON1 and CON2 be the same ideally, the firing phase angle θ of the BPP signal in the UP phase of the converters CON1, CON2 become as shown in Figs. a and b. That is, the firing phase θ of Up phase at the converter CON1 = 60°, and the θ of the Up phase of the converter CON2 = 30° to thus fire the thyristor.
