    Patent number: 4712171
    Abstract: A power source capable of providing a constant DC output when supplied with one of a range of AC inputs. Converter means providing a number of outputs of differing voltages each proportional to the input voltage. A number of parallel circuit lines each connected to one of those outputs. Each parallel circuit line including a rectifier, a maximum voltage regulator and a non-return current device. The outputs from those lines being connected to a common output to give the constant DC voltage supply.
