Charging apparatus and systems are provide for charging an energy storage system in respective vehicles using grid power where the vehicles are connected to the same transformer. The apparatus and system coordinate the charging and may use field weakening techniques to reduce a peak line-line…

A common-mode current sensor system and method for a traction inverter of an electric hybrid vehicle. The system and method detects/reduces excess common-mode currents that can be caused by the presence of alternating current (AC)-chassis type short circuit faults at the outputs of an inverter used…

Protection system and method for preventing damage to components in an inverter module caused by a permanent magnet (PM) electric machine being in an uncontrolled state is provided. The system has a back-up power supply to supply power to voltage rails for gate driver circuitry which controls at…

A system for controlling load sharing between multiple generators mechanically coupleable to the output shaft of a prime mover is provided. The system may comprise a first processor; and at least two inverters operably connectable to at least two generators, respectively. The generators provide AC…

A power supply includes an I/O module configured to receive a high voltage DC input and output a high voltage DC, a plurality of DC converter modules configured to receive the high voltage DC output from the I/O module and output a low voltage DC output, and a plurality of AC inverter modules…
