ABSTRACT:
A control system for a switching regulator which linearizes the relationship between the control input signal and the duty ratio of the pulse output. A logarithmic signal generator furnishes a logarithmically increasing signal to a comparator circuit. The comparator circuit compares the logarithmic signal to a control input signal and triggers a pulse generator such that the frequency of the pulses has an exponential relationship to the control input signal. The pulses are averaged and the average is subtracted from a reference signal. The result is then used as the input to the logarithmic signal generator. The resulting relationship between the duty ratio of the pulse output and the control input signal is linear.
