摘要： A digital controller includes a digital feedback circuit for use in generating a pulse-width modulated control signal. The signal is derived from binary signals representing a standard pulse-width signal for the rated output of the power supply plus a correction pulse-width signal reflecting the change in the output level of the power supply. Logic circuits alter the correction pulse-width signals to provide a balancing correction. Soft start operation of the power supply together with a selection of operating clock frequencies are also provided.

摘要： A digital controller used in regulating the output of a power supply including a diagnostic circuit for sensing the failure of a component in the power supply. Upon the occurrence of a fault, signals are generated locating the component which caused the shutdown of the power supply. The fault signals are inputted into a plurality of encoders which determine the priority between two or more simultaneous occurring faults and which further outputs binary signals identifying the faulty component. The binary signals are then latched and displayed in a LED display which may be actuated any time after the fault has occurred by the operation of a switch member.
