Abstract: A system for removing energy from an electrical choke is provided. The system includes one or more cores, at least one inductive coupling, and a resistor. The one or more cores are configured to form part of the electrical choke by generating magnetic energy. The at least one inductive coupling is operative to convert the magnetic energy into electrical energy. The resistor is electrically connected to the at least one inductive coupling and operative to dissipate the electrical energy as heat.

Abstract: A switching amplifier includes a power device and a processing device. The power device is configured for powering a load and is comprised of a plurality of switches. The processing device configured to calculate a switch junction temperature for a bonding wire in each switch based at least in part on a power loss of each switch; generate a first accumulated fatigue damage of the bonding wire in each switch based on the switch junction temperature; and generate an estimated remaining lifetime of the switching amplifier based on the first accumulated fatigue damages of the bonding wires in each switch.

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.
