Power supply for an aircraft

A system for an aircraft, the system comprising:

• at least one power bus configured to supply electrical power to one or more power consumers;
• at least one power supply comprising:
• a single input configured to receive electrical power from at least one energy source,
• an output for supplying electrical power,
• a plurality of converters, wherein each converter of the plurality of converters is electrically connected to the single input to receive the electrical power from the single input and is configured to convert the electrical power and provide the converted electrical power to the output, and
• a control unit configured to control each of the plurality of converters,
• wherein the control unit is configured to activate a first predefined number of converters of the plurality of converters when an indication for a current demand indicates a first value, and
• wherein the control unit is configured to activate a second predefined number of converters of the plurality of converters when the indication for the current demand indicates a second value, the second predefined number of converters being different from the first predefined number of converters;
• and
• a power distribution unit configured to electrically connect the at least one power supply to the at least one power bus.

A method of controlling a power supply, wherein the power supply comprises a single input configured to receive electrical power, an output for supplying electrical power, a control unit, and a plurality of converters, and wherein each converter of the plurality of converters is electrically connected to the single input to receive electrical power from the single input and is configured to convert the electrical power and provide the converted electrical power to the output, the method comprising:

• receiving, at the single input of the power supply, electrical power from at least one energy source,
• receiving, by the control unit of the power supply, an indication for a current demand, and
• individually controlling, by the control unit, each converter of the plurality of converters electrically connected to the single input, based on the indication for the current demand,
• wherein the control unit activates a first predefined number of converters of the plurality of converters when the indication for the current demand indicates a first value, and
• wherein the control unit activate a second predefined number of converters of the plurality of converters when the indication for the current demand indicates a second value, the second predefined number of converters being different from the first predefined number of converters.
