    Abstract: A vehicle includes a power source, a controller, a converter configured to receive a first voltage from the power source and to convert the first voltage to a second voltage, an auxiliary inverter system electrically coupled to an output of the converter and to an accessory having an electric motor, the auxiliary inverter system configured to convert the second voltage received from the converter for powering the electric motor, and a first communication link between the controller and the auxiliary inverter system. The auxiliary inverter system is further configured, responsive to interruption of the first communication link, to control a speed of the electric motor based on a level of the second voltage.

    Abstract: A power conversion system includes a bus bar, a switch coupled to the bus bar and configured to receive a DC input voltage from a voltage source through the bus bar, and a parallel fuse system. The parallel fuse system may be disposed on the bus bar in series with the voltage source and the switch. The parallel fuse system includes two or more parallel fuses, and may be configured for an inductance imbalance between the fuses, such that there is an asymmetric flow of currents through the fuses when the power conversion system is in operation. For the inductance imbalance, for example, the fuses may be positioned asymmetrically with regard to a shortest conductive path from the voltage source to the switch.

    Abstract: A system and method for auxiliary clutch failure detection determines a difference between a first output power of a powered system when a clutch system is controlled to engage and drive a load at a first output of the load and a second output power of the powered system when the clutch system is controlled to drive the load at a larger, second output. A control signal indicative of clutch failure is generated responsive to the difference being less than a designated threshold. The control signal may be used to implement one or more remedial actions.
