Abstract: A system for providing power to one or more loads. The system includes: a central controller configured to output a speed demand for one or more loads; and a plurality of power converters arranged in a parallel configuration with each other and configured to provide power to the one or more loads. Each power converter includes a speed control loop configured to calculate a local current demand based at least in part on an output speed error between the speed demand of the one or more loads and a measured speed of the one or more loads; a torque/current control loop configured to calculate an output voltage demand based at least in part on the local current demand of its respective speed control loop; and a module configured to modulate the output voltage of an inverter based on the output voltage demand from the torque/current control loop.

Abstract: A motor drive comprises a rectifier circuit portion arranged to receive an externally supplied AC voltage and to generate a DC bus voltage. An inverter circuit portion is arranged to receive the DC bus voltage (VDC_Bus) and to generate an AC output voltage (Vout) for supply to an external load. A DC bus portion is connected between the rectifier and the inverter. An inductor (L1) is connected in series along a bus conductor between the rectifier and inverter, and a DC link capacitor (C1) is connected in parallel between the bus conductors. A voltage across the DC link capacitor (C1) is input to a tuneable notch filter arranged to supply a filtered signal. A controller varies the resonant frequency of the notch filter to a plurality of values across an operational range and modulates a supply current provided by the inverter with a probe current signal at the resonant frequency.

Abstract: A proportional integrator for control of a motor drive arranged to be connected in parallel with one or more other motor drives to drive a common load. The proportional integrator includes means to receive an input command signal and to compare with a local measured signal from the motor drive and to output a local control signal for that motor drive, further comprising a global input signal indicative of the behaviour of the one or more other motor drives, the global input signal being incorporated into the proportional integral function with the input command signal and the local measured signal to provide the local control signal.

Abstract: An electric motor system that comprises a motor that comprises a rotor having a magnet mounted thereto and a stator that comprises one or more motor phase windings for driving rotation of the rotor when the motor phase windings receive an input voltage from an electrical power supply. The system has a controller that executes a back “EMF” observer that is operable to estimate a rotor angle by observing a back electromotive force induced in the stator by the rotor. Filtering is applied to the back EMF signal to reduce harmonics prior to determining the rotor angle.
