Patent ID: 8659185

Claim:
An electrical bus leveling unit comprising: a first power supply configured to generate electrical energy having a first set of electrical parameters and to store kinetic energy, wherein said first power supply comprises a compressed air powered aircraft turbine generator; a power converter electrically coupled to said first power supply, said power converter configured to convert the electrical energy having the first set of electrical parameters into an electrical energy having a second set of electrical parameters, said power converter configured to to be coupled to a main aircraft electrical bus couplable to a second power supply, the second power supply configured to operate with the second set of electrical parameters and the aircraft electrical bus being subject to experiencing relatively short term power transients due to the operation of equipment coupled to the aircraft electrical bus, wherein said power converter is a bi-directional power converter configured to optionally supply electrical energy to the aircraft electrical bus or transfer electrical energy from the aircraft electrical bus during a power transient; and a controller, comprising a processor, communicatively coupled to said first power supply and said power converter, said controller configured to: receive information relating to the operation of the aircraft electrical bus from a plurality of sensors; control an output of at least one of the first power supply and the power converter by enabling the kinetic energy stored in the first power supply to be converted into electrical energy to transfer electrical energy to the aircraft electrical bus when the second set of electrical parameters on the aircraft electrical bus is outside a predetermined range.
