Abstract

A power generation system is provided including a power boost regulator operative to provide load matched voltage operation of an AC power source.

First claim

What is claimed is:

1. A method of electrical power generation in a vehicle, the method including:
receiving, by a power boost regulator, alternating current (AC) power from an AC generator coupled to an output of an engine of a vehicle, the engine being operatively coupled to a ground engaging member of the vehicle to move the vehicle;
determining, by an electronic controller of the power boost regulator, a target current level and a target voltage level of power output by the AC generator based on a rotational speed of the engine;
controlling, by the power boost regulator, the AC generator to generate the AC power at the target current level and the target voltage level;
regulating, by the power boost regulator, the AC power to provide boosted direct current (DC) power for use by an electrical system of the vehicle; and
selectively distributing, by a power steering stage of the power boost regulator, the DC power to electrical loads of the vehicle based on a priority distribution schedule, wherein the electrical loads of the vehicle include an engine controller, at least one pump, and at least one chassis load and the engine controller has a higher priority than the at least one pump, and the at least one pump has a higher priority than the at least one chassis load.

2. The method of claim 1 , wherein the at least one pump includes a fuel pump and an oil pump, and the at least one chassis load includes at least one of a taillight, a handwarmer device, and a power relay for vehicle accessories.

3. A method of electrical power generation in a vehicle, the method including:
receiving, by a power boost regulator, alternating current (AC) power from an AC generator coupled to an output of an engine of a vehicle, the engine being operatively coupled to a ground engaging member of the vehicle to move the vehicle;
determining, by an electronic controller of the power boost regulator, a target current level and a target voltage level of power output by the AC generator based on a rotational speed of the engine;
controlling, by the power boost regulator, the AC generator to generate the AC power at the target current level and the target voltage level;
regulating, by the power boost regulator, the AC power to provide boosted direct current (DC) power for use by an electrical system of the vehicle; and
selectively distributing, by a power steering stage of the power boost regulator, the DC power to electrical loads of the vehicle based on a priority distribution schedule, wherein the electrical loads of the vehicle include an engine controller, at least one pump, and at least one chassis load, further including, in response to a startup event of the engine, distributing the DC power to the engine controller prior to distributing the DC power to the at least one pump and the at least one chassis load, and further including distributing the DC power to the at least one pump in response to the DC power distributed to the engine controller exceeding a power level threshold.

4. The method of claim 3 , wherein the startup event includes a manual recoil start by an operator.

5. A method of electrical power generation in a vehicle, the method including:
receiving, by a power boost regulator, alternating current (AC) power from an AC generator coupled to an output of an engine of a vehicle, the engine being operatively coupled to a ground engaging member of the vehicle to move the vehicle;
determining, by an electronic controller of the power boost regulator, a target current level and a target voltage level of power output by the AC generator based on a rotational speed of the engine;
controlling, by the power boost regulator, the AC generator to generate the AC power at the target current level and the target voltage level;
regulating, by the power boost regulator, the AC power to provide boosted direct current (DC) power for use by an electrical system of the vehicle; and
selectively distributing, by a power steering stage of the power boost regulator, the DC power to electrical loads of the vehicle based on a priority distribution schedule, wherein the electrical loads of the vehicle include an engine controller, at least one pump, and at least one chassis load, further including, in response to a startup event of the engine, distributing the DC power to the engine controller prior to distributing the DC power to the at least one pump and the at least one chassis load, and further including distributing the DC power to the at least one chassis load in response to the DC power distributed to the engine controller exceeding a first power level threshold and the DC power distributed to the at least one pump exceeding a second power level threshold.

6. A method of electrical power generation in a vehicle, the method including:
receiving, by a power boost regulator, alternating current (AC) power from an AC generator coupled to an output of an engine of a vehicle;
determining, by an electronic controller of the power boost regulator, a target current level and a target voltage level of power output by the AC generator based on a rotational speed of the engine;
controlling, by the power boost regulator, the AC generator to generate the AC power at the target current level and the target voltage level;
regulating, by the power boost regulator, the AC power to provide boosted direct current (DC) power for use by an electrical system of the vehicle; and
selectively distributing, by a power steering stage of the power boost regulator, the DC power to electrical loads of the vehicle based on a priority distribution schedule, wherein the electrical loads of the vehicle include an engine controller, at least one pump, and at least one chassis load, wherein the engine controller has a higher priority than the at least one pump, and the at least one pump has a higher priority than the at least one chassis load.
