Abstract

PURPOSE:To obtain a simple and high performance digital phase controlling circuit by comparing a digital controlling amount with a phase reference signal and forming a firing phase discriminator circuit of a read-only memory. CONSTITUTION:A phase reference is divided into thetaH, thetaL, a firing angle controlling amount is divided into alphaH, alphaL, the thetaL is compared with the alphaL by a comparator 14, the region of the firing angle controlling amount of the actuala value alphaH of the phase reference is discriminated at that time by the thetaH, and the firing timing and phase are discriminated by a firing phase discriminator circuit 15. This discrimination is performed by one type of pattern recognition by the ROM address.
