A three‑phase LLC converter is a high‑efficiency, high‑power DC‑DC resonant converter architecture that extends the concept of a traditional single‑phase LLC resonant converter into a three‑phase topology. It is the backbone of modern high-power DC-DC power stages due to their ability to deliver exceptional efficiency, high power density, and reliable soft-switching performance across wide operating conditions. With the growing demand for compact, energy-efficient power systems in EV charging, industrial, and energy storage applications, LLC topology has become the industry’s preferred choice for next-generation power electronics.
The eInfochips LLC Resonant Converter prototype is a compact yet high-performance solution, designed using the latest resonant power conversion techniques and safety-driven design practices. It enables Zero Voltage Switching (ZVS) across a wide load range, significantly reducing switching losses, thermal stress, and EMI.
