This article describes a feed forward/ feed back DC power regulator for controlling the firing angle of silicon-controlled rectifiers (SCRs) which couple an AC utility line source to a DC averaging filter. A feed-forward timing waveform derived directly from the AC line is compared to a conventionally derived feed-back output error signal.
