Abstract

PURPOSE:To perform closing angle control by detecting only ignition timing from pulselike input waveforms and by slicing a monotone function which starts syncronizing to ignition timing at the level of frequency-voltage transformer output. CONSTITUTION:A preceeding stage switching circuit FS consists of transisters Tr11 and Tr12 and switches the output of a pick-up coil of a signal generator SG. The base is connected to the pickup coil of the signal generator SG through registors R3 and R1 in series. It is also connected to the negative polarity side of a power source E through a diode D1. A defferential circuit DIF is a circuit which defferentiates the output of the preceeding stage switching circuit FS. A voltage comparison circuit COMP is circuit which compares the output of the defferential circuit DIF with that of a DC amplifier DA. A power switching circuit PS is a circuit which switches the output of the voltage comparison circuit COMP.
