This report is dealt with a firing circuit for SCR with compensation to the supply voltage variation, which is composed of magnetic amplifier of two full-wave types, namely Ramey type and self-saturation type.　This paper offers, first, the problem that the fluctuation of the reset flux change is caused by the a.c. supply voltage variation when the resistance of control circuit is small in the first stage of full-wave type magnetic amplifier. Secondly, a method of compensation for the fluctuation of the reset flux change is presented. By the experiments, it can be said that the fluctuation of load current of SCR amplifier is about +- 0.5% for the supply voltage variation of +-20%. Lastly, an analysis of this firing circuit is performed, and the control characteristics of SCR amplifier in the steady state are compared with experimental characteristics. Then, it is verified experimentally that the difference between calculated values and experimental results in the control characteristics is due to the residual flux of core.
