Abstract
In typical commercial/aerospace applications, synchronous generators provide power to both the high voltage and the low voltage loads. This disclosure describes a method of regulating the output voltage for all of the loads.
Claims17
A voltage regulator for a generator comprising:
- a high voltage line to supply three-phase AC power to a high voltage use, and a feedback link from said high voltage line to provide feedback to a control for the generator to achieve a desired voltage on said high voltage line;
- the high voltage line supplying a high voltage to be stepped down to a low voltage;
- a low voltage line receiving the low voltage for connection to a low voltage use;
- and
- a feedback line for providing feedback from said low voltage line to a low voltage control for controlling the level of voltage supplied on said low voltage line.
