Method for operating an electrical system
First Claim
1. A method for operating an electrical system for a machine, which electrical system includes at least one power source connected to a power-distribution network including a first portion with one or more power loads connected thereto and a second portion with one or more power loads connected thereto, the method comprising:
- during a power deficit, repeatedly executing a load-priority cycle, including;
operating in a first load-priority mode, including supplying power to the first and second portions of the power-distribution network, with a priority on supplying power to the first portion of the power-distribution network; and
subsequently, operating in a second load-priority mode, including supplying power to the first and second portions of the power-distribution network, with a priority on supplying power to the second portion of the power-distribution network.

Abstract
A method for operating an electrical system for a machine is provided. The electrical system may include at least one power source connected to a power-distribution network. The power-distribution network may include a first portion with one or more power loads connected thereto and a second portion with one or more power loads connected thereto. The method may include repeatedly executing a load-priority cycle including operating in a first load-priority mode and subsequently operating in a second load-priority mode, during a power deficit. Operating in the first load-priority mode may include supplying power to the first and second portions of the power-distribution network, with a priority on supplying power to the first portion. Operating in the second load-priority mode may include supplying power to the first and second portions of the power-distribution network, with a priority on supplying power to the second portion.

10. An electrical system for a machine, comprising:
-
a power-distribution network, including a first portion and a second portion;
one or more power sources connected to the first portion of the power-distribution network through a power converter and connected to the second portion of the power-distribution network through a connection other than the power converter;
one or more power loads connected to the first portion of the power-distribution network;
one or more power loads connected to the second portion of the power-distribution network; and
power-supply controls configured to execute a control method including;
adjusting an output voltage at which the power converter supplies power to the first portion of the power-distribution network dependant upon power demands of one or more of the power loads connected to the second portion of the power-distribution network. - View Dependent Claims (11, 12, 13, 14, 15)

16. A machine, comprising:
-
a driving system;
an electrical system, including;
one or more power sources;
a power-distribution network, including a first portion connected to one or more of the power sources and a second portion connected to one or more of the power sources;
one or more power loads connected to the first portion of the power-distribution network;
one or more power loads connected to the second portion of the power-distribution network;
power-supply controls configured to execute a control method including;
when the driving system is operating, operating in a first load-priority mode, including supplying power to the first and second portions of the power-distribution network with a priority on supplying power to the first portion of the power distribution network; and
when the driving system is not operating, selectively operating in the first load-priority mode or a second load-priority mode dependent upon conditions of operation of the machine, wherein the second load-priority mode includes supplying power to the first and second portions of the power-distribution network with a priority on supplying power to the second portion of the power-distribution network. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)
