The Relationship Between ESR and ESL of Thermal Loop PCBs and Via Arrangement
Abstract This paper investigates the critical relationship between Equivalent Series Resistance (ESR) and Equivalent Series Inductance (ESL) in thermal loop printed circuit boards (PCBs) and their dependence on via arrangement strategies. As power electronics continue to advance with higher frequencies and greater power densities, understanding and optimizing the parasitic elements introduced by vias becomes increasingly…
