Abstract
An improved EPGS with an integrated electrical system architecture uses SPDAs with localised power converters to provide the necessary types of power to their respective electrical loads so that a single type of primary power bus may be used to connect its PDAs to respective SPDAs.
Claims20
An electrical power generating system (EPGS) for an aircraft with an integrated electrical system architecture that has at least one electrical power source aboard the aircraft, comprising:
- a primary power distribution assembly (PDA) aboard the aircraft for each electrical power source that distributes power of one type to a single corresponding primary bus;
- and
- at least one secondary power distribution assembly (SPDA) aboard the aircraft for each PDA that receives only the power of one type on the single corresponding primary bus, converts power of the one type to converted power of multiple other types, wherein at least one type of converted power is a type of AC power and distributes the converted power of the multiple other types to at least some respective electrical loads for each SPDA.
An electrical power generating system (EPGS) for an aircraft with an integrated electrical system architecture that has at least one electrical power source aboard the aircraft, comprising:
- a primary power distribution assembly (PDA) aboard the aircraft for each electrical power source that distributes AC power to a single corresponding primary bus;
- and
- at least one secondary power distribution assembly (SPDA) aboard the aircraft for each PDA that comprises a power converter that receives only the AC power on the single corresponding primary bus, simultaneously converts it to multiple types of converted power, wherein at least one type of converted power is a type of DC power and distributes the converted DC power to at least some respective electrical loads for each SPDA.
An electrical power generating system (EPGS) for an aircraft with an integrated electrical system architecture that has at least one electrical power source aboard the aircraft, comprising:
- a primary power distribution assembly (PDA) aboard the aircraft for each electrical power source that distributes DC power of high electrical potential to a single corresponding primary bus;
- and
- at least one secondary power distribution assembly (SPDA) aboard the aircraft for each PDA that comprises a power converter that receives only DC power of high electrical potential on the single corresponding primary bus, simultaneously converts it to multiple types of power, wherein at least one type of converted power is a type of AC power and distributes the converted AC power to at least some respective electrical loads for each SPDA.
An electrical power generating system (EPGS) for an aircraft with an integrated electrical system architecture that has at least one electrical power source aboard the aircraft, comprising:
- a primary power distribution assembly (PDA) aboard the aircraft for each electrical power source that distributes DC power of high electrical potential to a single corresponding primary bus;
- and
- at least one secondary power distribution assembly (SPDA) aboard the aircraft for each PDA that comprises a power converter that receives only DC power of high electrical potential on the single corresponding primary bus, simultaneously converts it to multiple types of power, wherein two types of converted power comprise AC and DC power of lower electrical potential and distributes the converted AC and DC power of lower electrical potential to at least some respective electrical loads for each SPDA.
