Abstract
A power supply system includes a set of power supply units, each power supply unit arranged electrically in series and defining a common power supply, each power supply unit having a power module and a selective bypass for selectively bypassing the respective power module. The power supply system can meet a power demand.
Claims16
A dynamic power supply system, comprising:
- a set of power supply units arranged electrically in series and defining a common direct current (DC) power supply system output, each of the set of power supply units including:
- a power module having a set of energy storage units;
- a DC to DC power converter connected with the power module and an energy storage unit power output;
- and
- a selective bypass arranged to controllably bypass the power module across the energy storage unit power output;
- and
- a controller module communicatively connected with each respective DC to DC power converter and the selective bypass, and configured to operate at least a first subset of the energy storage units to operably supply energy by way of operating the respective subset of the DC to DC power converters, to operate at least a second subset of the energy storage units to operably bypass the respective subset of the selective bypasses, and to operate the first subset of the energy storage units by way of interleaving a pulse width modulation, whereby the operating the first subset of the energy storage units operably reduces an output DC voltage ripple at the common DC power supply system output.

A dynamic power supply system for an aircraft power distribution system, comprising:
- at least one generator;
- a direct current (DC) power bus selectively connecting the at least one generator with at least one electrical load;
- a set of power supply units arranged electrically in series and defining a common DC power supply system output selectively connecting with the DC power bus, each of the set of power supply units including:
- a power module having a set of energy storage units;
- a solid-state DC to DC power converter connected with the power module and an energy storage unit power output, each of the DC to DC power converters rated to supply 50 Volts DC at the respective energy storage unit power output;
- and
- a selective bypass arranged to controllably bypass the power module across the energy storage unit power output;
- and
- a controller module communicatively connected with each respective DC to DC power converter and the selective bypass, and configured to determine a presence of a supplemental power demand, and in response to determining the presence of the supplemental power demand, operate at least a first subset of the power supply units to operably supply supplemental energy to the DC power bus by way of operating the respective subset of the DC to DC power converters, and to operate at least a second subset of the power supply units to operably bypass the respective subset of the selective bypasses such that power supplied at the common DC power supply system output meets the power demand.
