Abstract

A control system for controlling a DC-DC voltage converter circuit is provided. An output voltage controller outputs a DC-DC voltage converter control voltage to an input control terminal to increase a switching duty cycle within the DC-DC voltage converter circuit when the low voltage is less than an output reference voltage. An input voltage controller reduces the DC-DC voltage converter control voltage at the input control terminal of the DC-DC voltage converter circuit when a high voltage is less than an input reference voltage to reduce the switching duty cycle within the DC-DC voltage converter circuit.
