Abstract: A diagnostic device for diagnosing a faulty condition in a gradient amplifier system is presented. The diagnostic device includes a first current sensor configured to be coupled to an input terminal of a filter unit, where the first current sensor is configured to measure a first electric current at the input terminal of the filter unit, and where the first electric current includes a high frequency current component and a low frequency current component. Further, the diagnostic device includes a diagnostic unit coupled to the first current sensor and configured to determine an impedance across the filter unit and a load unit based on the low frequency current component of the measured first electric current and a pre-stored reference voltage, and diagnose the faulty condition of at least one component in at least one of the filter unit and the load unit based on a characteristic of the determined impedance.

Abstract: In a magnetic resonance imaging (MRI) system, synchronized control of the operation of a gradient amplifier subsystem, a power supply subsystem, and a power distribution unit subsystem is accomplished by providing a coil command reference signal as an input to respective control blocks of the gradient amplifier subsystem, the power supply subsystem, and the power distribution unit subsystem. The coil command reference signal corresponds to a predetermined gradient coil current for at least one gradient coil of a scanner of the MRI system.

Abstract: Embodiments of the present disclosure include an inductor including at least one inductor coil, the at least one inductor coil including a plurality of outer longitudinal portions aligned around an outer periphery of the inductor, and a plurality of inner longitudinal portions aligned around an interior of the inductor. The plurality of outer longitudinal portions and the plurality of inner longitudinal portions collectively form two width-wise sides of the inductor and two length-wise sides of the inductor. The two width-wise sides and the two lengthwise sides define a substantially rectangular prism shape. The two width-wise sides and the two lengthwise sides define a hollow inductor core.

Abstract: The present disclosure presents techniques to facilitate improving operation of an electrical system, which includes a bus structure that cascades multiple electrical devices. The bus structure includes a first outer conductive layer implemented as a positive layer; a second outer conductive layer implemented as a negative layer; a first intermediate conductive layer neighboring the first outer conductive layer; a second intermediate conductive layer neighboring the second outer conductive layer; and a third intermediate conductive layer neighboring the second intermediate conductive layer, in which the third intermediate conductive layer is implemented as an inter-device layer that facilitates electrically coupling at least two of the electrical devices in series. The first intermediate conductive layer is implemented as a negative layer and the second intermediate conductive layer is implemented as a positive layer to facilitate reducing stray inductance and/or increasing stray capacitance introduced in the electrical system during operation.
