Abstract
A dc power supply system comprising two or more voltage regulator units connected in parallel to a common load, there being at least one more regulator unit provided than is required to meet the rated load current requirement. The spare or redundant regulator assumes the load automatically if another regulator fails, and does so in a manner such that it does not interfere with operation of other regulators when they are operating normally and such that its own operation is not affected by the others in the event of their failure. To these ends the power supplies include a decoupling network which is associated with each of the regulators and which operates to prevent any reverse flow of current to that regulator, thus isolating it in the event of its failure, and they include also keep-alive circuitry which forces the redundant or spare power supply to produce an output at all times, to thus enhance its capability to pick up the load instantaneously and with minimized transient in load voltage should one of the other regulators fail.
