Abstract
A power generation system is described for supplying electrical power to a load from at least one of a generator and a battery. The power generation system includes a power bus coupled to the generator and a bi-directional conversion unit coupled between the power bus and the battery. The bi-directional conversion unit is capable of transitioning between a first direction wherein electrical power flows from the power bus to the battery and a second direction wherein electrical power flows from the battery to the power bus.
Claims28
A power generation system comprising:
- a generator to generate electrical power;
- a DC storage or source device (DCSSD);
- a power bus coupled to said generator;
- and
- a bi-directional conversion unit coupled between said power bus and said DCSSD, said bi-directional conversion unit comprising a bi-directional circuit having switching elements, and a controller to generate control signals to selectively activate the switching elements to control a direction and amount of electrical power flowing between said DCSSD and the power bus through said bi-directional current circuit, wherein in a first direction power flows from said power bus to said DCSSD and in a second direction power flows from said DCSSD to said power bus.
A power generation system comprising:
- a generator to generate electrical power;
- an electronic control unit coupled to said generator, said electrical control unit containing a power supply bus;
- and
- a bi-directional conversion unit comprising a bi-directional power supply circuit coupled between said power bus and a battery, said bi-directional power supply circuit capable of transitioning between a first direction wherein electrical power flows from said power bus to a battery and a second direction wherein electrical power flows from said battery to said power bus.
A method of generating power comprising:
- generating electrical power;
- charging a power bus using the electrical power generated;
- charging a battery using the electrical power from said power bus if a voltage level of said power bus exceeds an upper threshold value;
- charging said power bus using the electrical power from said battery if the voltage level of said power bus drops below a lower threshold value;
- and
- adjusting the electrical power generated if load demand exceeds the electrical power generated and the electrical power supplied by the battery.
A system comprising:
- at least one electrical power storage device;
- at least one electrical power source device;
- at least one load;
- and
- a power supply controller coupled between said at least one electrical storage device and said at least one electrical source device to control the flow of electrical energy between said storage device and said source device and to control the flow of electrical energy demanded by said at least one load from at least one of said storage and source devices.
