The regulator employs the flyback phenomenon of an inductor to boost the input voltage and provide a regulated output voltage. A single high frequency, high power, low saturation resistance, switching transistor is used to connect the inductor in the charge and discharge or flyback circuits. A high speed, high gain, semiconductor feedback circuit detects changes in the output voltage and controls the charge and flyback times of the inductor to provide a regulated output voltage. The performance is shown by curves of the efficiency, ripple, and output voltage. These curves reveal the efficiency to be greater than 90 percent for a load of 60 to 100 percent of the maximum output power rating (44 watts) with an input of 12 to 20 volts.
