ABSTRACT:
A controller for controlling SCR's used for supplying power to loads, which provides digital control of the phase angle of the firing signal for SCR's during rapidly changing frequency of applied power. The digital control is based upon clocking signals which are derived directly from the rotation of a generator to always provide a set number of pulses for each electrical cycle independent of time (frequency).
