Abstract
A method and apparatus for a power distribution system, includes providing, from a power source having a set of dischargeable power storage devices connected by way of selectable connections, a power supply to a voltage output, and switchably connecting the voltage output to a set of power outputs having different electrical characteristics.
Claims20
A power supply for a set of power outputs having a first electrical characteristic and a second electrical characteristic, comprising:
- a set of power storage units arranged in series, each power storage unit having a respective direct current (DC) dischargeable power storage device, a first selectable connection configured to enable a voltage output of the respective power storage device, and a second selectable connection configured to enable bypassing the voltage output of the respective power storage device;
- a controller module communicatively connected with the set of first selectable connections and the set of second selectable connections and configured to selectively enable at least a subset of the first selectable connections or a subset of the second selectable connections, wherein the selective enabling enables the providing of the first electrical characteristic or the second electrical characteristic by way of the set of power storage units;
- and
- a common voltage output for the set of power storage units configured to be switchably connected with the set of power outputs, wherein the common voltage output provides at least one of the first electrical characteristic or the second electrical characteristic to the set of power outputs.
A method of supplying power to a set of switchably connectable power outputs having a first electrical characteristic and a second electrical characteristic, the method comprising:
- selectively enabling, by a controller module, one of a voltage output connection or a bypass connection for each of a set of dischargeable direct current (DC) power storage units arranged in series such that the selective enabling enables the providing of the first electrical characteristic or the second electrical characteristic by way of the set of power storage units to the set of power outputs;
- and
- providing a summated output of the set of power storage units by way of a common voltage output of the set of power storage units to the set of switchably connectable power outputs, wherein the common voltage output provides at least one of the first electrical characteristic or the second electrical characteristic.
A power supply for a set of power outputs having a first electrical characteristic and a second electrical characteristic, comprising:
- a set of power storage units arranged in series, each power storage unit having a respective direct current (DC) dischargeable power storage device, a first selectable connection configured to enable a voltage output of the respective power storage device, and a second selectable connection configured to enable bypassing the voltage output of the respective power storage device;
- a controller module communicatively connected with the set of power storage units and configured to selectively enable at least a subset of the first selectable connections or a subset of the second selectable connections thereby forming at least one of an alternating current (AC) voltage waveform or a direct current (DC) voltage waveform by way of the set of power storage units;
- and
- a common voltage output for the set of power storage units configured to be switchably connected with the set of power outputs, wherein the common voltage output provides the at least one of the AC voltage waveform or the DC voltage waveform.
