摘要： A program product for determining an obstruction in an air circuit for an environmental control unit having a motor is provided. The program product comprises a program and a non-transitory, computer-readable storage medium. The program is configured to at least facilitate obtaining a load current of the motor, determining a state of the motor, generating a comparison, and determining the obstruction using the load current and the comparison. The comparison is generated by comparing the load current to a first plurality of values if the motor is in a steady state, and by comparing the load current to a second plurality of values if the motor is in a transient state. The non-transitory, computer-readable storage medium stores the program.

摘要： Methods for active power management, i.e., the power management method may be activated in response to changes in the supply and demand of power in a system, are disclosed. The power management method may use dynamically collected data reporting levels of electrical power utilized by systems while matching them to the available power. One embodiment of the present invention may be applied in smaller or medium sized systems. Another embodiment of the present invention may be implemented making use of additional aircraft resources, such as an integrated modular avionics (IMA) line replaceable unit (LRU) in larger sized systems. Both of these embodiments may make use of data collected from systems utilizing or generating electrical via the bus power control unit (BPCU) LRU, the data processing taking place either locally in the BPCU (small or medium sized systems) or in the IMA (larger systems).

摘要： A multi-functional AC to DC converter (100) controls AC to DC conversion as a function of at least one characteristic of a battery (200) connected to a DC power bus (300), such that the voltage output by the converter (100) to the DC power bus (300) is varied to efficiently charge the battery (200). In one implementation of the present invention, a multi-functional AC to DC converter (100) also adjusts the voltage output to the DC power bus based on a starting condition of an auxiliary power unit (400) so that the supplied voltage is suitable for starting the APU (400). The present invention is suitable for implementation in an aircraft power system to maintain the voltage output within the compliance range of the DC power bus (e.g., between 27.5 and 29 Vdc) while adjusting the output voltage to efficiently charge a battery (200) connected to the bus (300) and/or start an APU (400) connected to the bus (300).

摘要： A power management system may employ a power source, a distribution system between the power source and electrical loads and an energy accumulator. The accumulator may comprise a plurality of energy processing blocks. Each block may have a limited number of energy storage cells connected in series to produce first voltage. A second higher output voltage from the accumulator may be achieved though integrated DC-DC, DC-AC and AC-DC conversion with intermediate boost of AC voltage through high frequency transformers. Bidirectional power flow may be achieved with high efficiency during charge and discharge of the accumulator. Secondary windings of the transformers may be connected with one another in series so that the accumulator can transfer energy between the distribution system and any one or all of the energy processing units in a fault-tolerant and efficient manner.

摘要： An ungrounded or floating DC electrical power distribution system may experience a single line to ground fault. Such a fault may not disrupt operation of the system, but its presence may raise a risk of additional problems if left uncorrected. A system for progressively grounding the ungrounded system may be initiated when a line to ground fault is suspected based on the voltage difference measured to a common chassis point. As grounding through successively lower impedance proceeds, fault current may increase and detection of severity of the line to ground fault may be more readily achieved, thus facilitating localization of the fault. Localization may be achieved through an analysis of direction of capacitive currents in isolatable zones of the system.

摘要： A method and apparatus of determining the state of charge and charging Li-ion batteries while the batteries remain floating on the direct current (DC) bus without the need for a dedicated charger is described. The system includes a battery, a DC generator and a converter, each electrically connected to a DC bus. A charging control algorithm may be used to monitor and control the charging current supplied to the battery. The voltage on the DC bus may be varied to help control the charging current supplied to the battery, based on the battery's internal impedance and the battery's state of charge.
