Abstract: A three-phase current sensor for measuring currents running in three conductors of a three-phase conductor system includes at least a first magnetic measuring device. The magnetic measuring device includes a magnetic circuit provided with at least two gaps and a magnetic field sensor arranged in each gap of the magnetic circuit. The magnetic field sensors are positioned on both sides of a cavity sized to receive one of the three conductors. The gaps and thus the magnetic field sensors are positioned such that stray magnetic flux from an adjacent conductor has substantially equal amplitude passing through each of the sensors.

Abstract: Power inverter assemblies are provided herein for use with motor vehicles. An inverter assembly may have a symmetrical structure configured to convert DC input power to AC output power. The inverter assembly may include a housing enclosing a symmetrical DC input portion, a symmetrical AC output portion, a DC link capacitor, and a gate drive portion having a pair of power modules. The symmetrical DC input portion can include a DC input bus bar sub-assembly to which the DC link capacitor is coupled, and a second DC bus bar sub-assembly that may electrically couple the DC link capacitor with the power modules. The symmetrical AC output portion may include a three phase output AC bus bar sub-assembly to which the power modules can be electrically coupled. A cooling sub-assembly may be provided for cooling the power modules with fluid transfer using a coolant.
