Radial Half-Bridge Layout for Uniform Current Sharing

The patent applies asymmetry by strategically positioning transistor devices at different radial distances from the central output connector. Specifically, devices are arranged with varying distances (e.g., first distance for high-side switches, second distance for low-side switches) to compensate for inherent circuit asymmetries and achieve uniform current sharing. This deliberate asymmetric layout counterbalances the natural current distribution imbalances that would otherwise occur in parallel configurations.

The patent implements equipotentiality by ensuring that all transistor devices are positioned to have equal electrical potential conditions relative to the output connector. This is achieved through careful control of trace lengths, via placements, and grounding arrangements so that each device experiences identical voltage drops and impedance conditions, thereby enabling uniform current sharing across all parallel devices.

The patent applies segmentation by dividing the circuit layout into distinct radial zones around the central output connector. Devices are grouped into segments at different radial distances, with each segment optimized for specific functions (e.g., high-side switches at one distance, low-side switches at another). This segmented approach simplifies the overall layout design by creating modular, repeatable patterns rather than requiring unique positioning for each device.

The patent transitions from a conventional planar two-dimensional layout to a radial three-dimensional arrangement around a central output connector. By organizing devices in concentric rings at different radial distances and angular positions, the design achieves better current sharing uniformity while maintaining manageable complexity through the inherent symmetry of the radial geometry. This dimensional reorganization allows multiple devices to be equidistant from the output in a natural, scalable pattern.
