Abstract
A method of regulating the output voltage of an electric power source combines a status signal representative of the output voltage of the power source with a reference signal to produce a first control signal. A status signal representative of the output current of the power source is combined with the reference signal to produce a second control signal. A bias voltage signal is applied to a junction point and the first and second control signals are connected through an OR network to the junction point, thereby forming an output signal at the junction point. The power source output is then controlled in response to this output signal. Under normal operating conditions, the magnitude of the control signal corresponding to the power source output voltage is less than the magnitude of the bias voltage signal, and the magnitude of the control signal representative of current is greater than the magnitude of the bias voltage signal, such that the voltage sensing loop is in control of the power source output.
