SYSTEM AND METHOD PROVIDING OUTPUT SIGNAL CONTROL FOR A POWER SUPPLY

摘要

A control system for selectively isolating a power supply from a common bus is provided. The control system comprises a connection to an output path of an output signal of the power supply and a resistive element providing a variable resistance between an input terminal and an output terminal. The input terminal is connected to the connection and the output terminal is connected to the common bus. The resistive element furthe r comprises a control terminal allowing adjustment of the variable resistance. A control element provides a control signal to the control terminal; the control element is responsive to current flowing between the output path and the common bus.
