EIS Current Calibration Using Parallel Sense Resistors

The patent divides a single high-power shunt resistor into multiple lower-power sense resistors connected in parallel. Each sense resistor handles a portion of the total current, allowing the use of smaller, more accurate resistors with lower inductance. This segmentation resolves the contradiction by maintaining measurement accuracy while avoiding the non-linear scaling issues of single high-power resistors.

The patent combines multiple sense resistors in parallel to achieve the required current handling capability. By merging multiple low-inductance resistors, the system achieves both the high current capacity and the low inductance needed for accurate EIS measurements, resolving the contradiction between measurement precision and device complexity.

The patent segments the power handling requirement across multiple sense resistors. Each resistor dissipates a fraction of the total power, reducing individual power dissipation losses. The parallel arrangement allows the system to handle high total current while minimizing overall power loss through efficient current distribution.

By merging multiple low-power resistors in parallel, the system achieves high current handling capacity while maintaining low power dissipation. The combined arrangement distributes the power load, reducing total energy loss compared to a single high-power resistor, thus resolving the contradiction between power capacity and energy loss.

The patent segments the inductance contribution by using multiple small resistors instead of one large resistor. Each small resistor has lower parasitic inductance, and when connected in parallel, the total inductance is further reduced. This maintains the required current measurement range while minimizing inductance effects that would otherwise degrade EIS measurement accuracy.

The patent combines multiple low-inductance sense resistors in parallel to achieve both wide current measurement range and high measurement precision. The parallel configuration reduces total inductance while maintaining current handling capability, resolving the contradiction between adaptability and measurement precision.

The patent segments the measurement function across multiple resistors, with each resistor contributing to the overall measurement. The segmentation is managed through a systematic parallel arrangement that, while increasing component count, provides benefits in accuracy and power distribution that justify the increased complexity.

The patent merges multiple sense resistors into a unified parallel measurement system. This combining approach achieves improved measurement precision and power dissipation characteristics, with the merged system presenting a single functional interface that manages the underlying complexity internally.
