DEVICE FOR DISPLAYING IGNITION AND CONDUCTION COMPLETION PHASE ANGLES

摘要

In an apparatus wherein electric power is supplied through a thyristor device operated under the control of an ignition instruction control circuit, use is made of a device for displaying ignition phase angle and conduction completion phase angle which comprises a circuit for detecting the operational condition of the thyristor. The output of the circuit is connected to a circuit for detecting the conduction completion phase angle of the thyristor, and the outputs of the latter circuit and the ignition instruction control circuit are converted in another circuit into values indicative of the ignition phase angle and the conduction completion phase angle which are to be displayed.
