    Abstract: A system for controlling multiple inverter-driven loads includes a controller that is configured to be coupled with an inverter that receives direct current and converts the direct current into an alternating current in order to supply the alternating current to plural loads that are connected to the inverter by plural respective contactors. The controller also is configured to control operations of the inverter and of the contactors in order to individually control which of the loads remain connected to and powered by the inverter and which of the loads are disconnected from the inverter.

    Abstract: A system (for controlling cooling of an alternator) comprises a control system, an alternator, and a blower fan, the alternator having a stator and a rotor. The control system is adapted to estimate one or more temperatures of the stator and/or rotor of the alternator using a thermal model. The control system is also adapted to control the blower fan to cool the alternator by providing a specified amount of air flow across the stator and rotor of the alternator, based on the estimated one or more temperatures of the stator and/or rotor.

    Abstract: A vehicle brake control system includes an inverter configured to convert direct current (DC) into an alternating current (AC) for a motor of a vehicle. The inverter includes switches configured to convert the DC to the AC, as well as a resistor and a bypass switch disposed in series with each other. A controller is communicatively coupled with the inverter switches and the bypass switch. The controller opens the bypass switch so that the DC is conducted through and converted into the AC for the motor during a motoring mode. The controller closes the bypass switch so that regenerated current from the motor is conducted through the resistor of the inverter for partial dissipation of the regenerated current during a dynamic braking mode.

    Abstract: Methods for detecting a short fault of an alternator rectifier electronic component include sampling a field winding voltage or current signal of an alternator, during operation of the alternator, and determining a fault ripple period at which the alternator field winding signal exceeds a fault threshold. A short fault of an electronic component of a rectifier coupled to the alternator is detected in the event that the fault ripple period closely matches an alternator armature period. Alternatively or additionally, the sampled field winding signal is band pass filtered, and a short fault is detected in the event that an amplitude of the band pass filtered field winding signal exceeds a fault threshold. The methods can be implemented, for example, by an apparatus that includes a hysteresis frequency counter, a frequency comparator, and a countdown timer.
