ABSTRACT:
A system for connecting a receiver to a redundant power supply. The power supply units are connected to the receiver by means of a pair of control switches, each being connected in series between one of the power units and the receiver, and each having its intrinsic diode forwardly biased between the power unit and the receiver. A voltage comparator senses which of the power supply units is having the higher potential difference between its high and low potential terminals. The output of the comparator controls the gate of both control switches such that the control switch in series with the sensed power supply unit is conducting while the other one is off. When a reversed polarity is applied to the receiver, the receiver is protected by the intrinsic diode. When at least one of the power supplies is connected with the correct polarity, the receiver is supplied without an appreciable voltage drop and with the lowest possible power losses.
