Abstract
A method for providing electrical power to two loads on a powered system/unit, the method including supplying electrical power from a first phase and a second phase of a three-phase inverter to a first load, supplying electrical power from the second phase and a third phase of a three-phase inverter to a second load, and independently controlling the first phase and the third phase of the electrical power to comply with an electrical requirement of the first load and/or the second load. The two loads may be DC loads that require DC power for operation, or the loads may be AC loads that require two-phase power for operation. A system for providing electrical power to two loads on a powered unit is also disclosed.
Claims19
A method for providing electrical power to two loads on a powered system, the method comprising:
- supplying first electrical power from a first phase and a second phase of a three-phase inverter to a first load;
- supplying second electrical power from the second phase and a third phase of the three-phase inverter to a second load;
- and
- independently controlling the first phase and the third phase of the three-phase inverter to comply with one or more electrical requirements of the first load and/or the second load.
A method for providing electrical power to loads in a powered system, the method comprising:
- converting electrical power of a first phase and a second phase of a three-phase inverter to a first DC signal, the first DC signal being supplied to a first true DC load requiring the first DC signal for operation;
- converting electrical power of a third phase and the second phase of the three-phase inverter to a second DC signal, the second DC signal being supplied to a second true DC load requiring the second DC signal for operation;
- and
- independently controlling the first phase and the third phase of the three-phase inverter to comply with one or more electrical requirements of the first true DC load and/or the second true DC load.
A system for providing electrical power to two loads on a powered unit, the system comprising:
- a three-phase inverter configured to supply first electrical power from a first phase and a second phase of the three-phase inverter to a first load and second electrical power from the second phase and a third phase of the three-phase inverter to a second load;
- and
- a controller configured to control the first phase and the third phase of the three-phase inverter to comply with one or more electrical requirements of the first load and/or the second load.
