    摘要： A power electronic device is disclosed. The power electronic device may include a housing, a conductive element positioned within the housing and rated for at least a medium voltage, a cooling system in fluid communication with the conductive element, a plurality of temperature sensing tags and a data collection unit having a receiver that is configured to receive signals from the antennae of the temperature sensing tags. The cooling system may have a plurality of outlet conduit elements that are positioned within the housing. Each of the tags may be attached to one of the outlet conduits and may include a power supply, a temperature sensor, and an antenna.

    摘要： Systems and method for controlling an alternating current (AC) electrodynamic machine (390) with a variable frequency drive (VFD) (380) include a control system (300) with a phase-locked-loop (PLL) circuit (382) for providing a stator flux angle signal (338) to the VFD (380), the PLL circuit (382) comprising a proportional integral (PI) regulator (332) providing an output signal (334); and a feedforward generator (350) in communication with the PLL circuit (382), wherein the feedforward generator (350) tracks a stator flux position of the AC electrodynamic machine (390) such that the feedforward generator (350) determines a stator frequency signal (352) based on stator flux signals (308, 310, 312) and supplies the stator frequency signal (352) downstream of the PI regulator (332), and wherein the stator frequency signal (352) is summed with the output signal (334) of the PI regulator (332) to provide a dynamically adapted output signal (335) of the PI regulator (332), and wherein the adapted output signal (335) is used to determine the stator flux angle signal (338).
