摘要： A system and method for providing power to a vehicle is disclosed. The system can include a plurality of parallel module converter modules (“modules”) each capable of supplying a predetermined electrical load. The plurality of parallel module converter modules can be networked to form a parallel module converter (“converter”) for prioritizing and allocating each electrical load to one or more parallel module converter modules. Each module can include an internal protection controller and a logic controller. The individual modules can provide power to various loads in the vehicle either alone, or in concert with other modules. The system can enable fewer power controllers to be used, saving weight and time. The controllers in the system can also be utilized at a higher level reducing unnecessary redundancy.

摘要： An electric drive system including an impedance balancing noise filtering circuit is disclosed. The electric drive system includes a direct current (DC) power source configured to output DC power to an output port and an inverter configured to convert the DC power output by the DC power source into alternating current (AC) power that is provided to an input port of an AC load. The impedance balancing noise filtering circuit includes an impedance bridge electrically intermediate the output port of the DC power source and the input port of the AC load. The impedance balancing noise filtering circuit includes different sets of passive components that are positioned on both the DC-side and the AC-side of the inverter. These sets of passive components are configured to facilitate impedance balancing that reduces common-mode (CM) electromagnetic interference (EMI) emission at the output port of the DC power source.

摘要： Provided is a low-weight, high-efficiency inductor design for use with or in electrical power equipment, such as inverters. A toroidal power inductor includes a support structure comprising an outer shell, an inner shell, and one or more coolant channels formed therebetween, a plurality of conductors wrapped around and supported by an exterior surface of the outer shell, and an interior cavity substantially enclosed by the inner shell of the toroidal support structure. The plurality of conductors are configured to provide an inductance for the toroidal power inductor, and the one or more coolant channels are distributed beneath the exterior surface of the outer shell to cool the plurality of conductors. An air-core power inductor may implement the conductors using high-temperature superconducting (HTS) tapes cooled by cryogenic fluid flowing within the coolant channels.

摘要： A synchronous brushless machine having a single exciter field stator winding. The single exciter field stator winding is energized by a high frequency alternating current to provide a single excitation field to magnetically couple with the exciter field armature winding in both the starter mode and the generator mode. With a higher excitation frequency relative to the main armature current frequency, a steady main field voltage can be achieved which improves stability control while in the starter mode. In one or more configurations, the single exciter field stator winding is driven by a H-bridge converter.

摘要： Methods and apparatus for detecting and characterizing arc faults in an aerospace electric propulsion system and then coordinating the operation of various elements of the protection system to execute a fault-clearing sequence. In a current-based method, the arc is detected and characterized based on differential readouts from current sensors. The difference between currents measured at two ends of a protection zone are compared to a difference threshold. In a power-based method, the arc is detected and characterized based on differential readouts from voltage and current sensors. The differential voltage and current readouts are used to compute the respective powers at two ends of a protection zone. The difference between the respective powers is integrated over a period of time and then the integrated difference is compared to a difference threshold. A differential protection trip mode is invoked when the difference threshold is exceeded.
