Abstract
The output voltage of a dc—dc transformer having a ratio of approximately m/n, and which is powered from a main power supply having a remote sense input, can be stabilized by feeding the output of the dc—dc transformer to the remote sense input of the main power supply through an amplifier having a voltage gain of m/n.
Claims2
A distributed power system having an output voltage which is stabilized comprising
- a main power supply having a main power supply output voltage and a remote sense input,
- at least a first dc—dc transformer having a dc—dc transformer input voltage which is connected to the main power supply output voltage and having a dc—dc transformer output voltage which is an output voltage of the distributed power system,
- and an amplifier means having an amplifier input which is connected to dc—dc transformer output voltage of the at least a first dc—dc transformer and having an amplifier output which is connected to the remote sense input of the main power supply,
- the at least a first dc—dc transformer further having the ratio of its dc—dc transformer input voltage to its dc—dc transformer output voltage equal to m/n, where m is the nominal value of the dc—dc transformer input voltage and n is the desired value of the dc—dc transformer output voltage, and
- the amplifier means having a gain of m/n,
- so as to adjust the main power supply output voltage by varying the remote sense input to stabilize the output voltage of the distributed power system.
