Sparsity in power system

Web13. apr 2024 · This is due to the fact that when multiple power modules are connected in parallel, they all share the same current path. As a result, each module contributes to the total stray inductance of the power system. To minimize the effect of parallel devices on the stray inductance, it is important to consider their impact when designing a power system.
