DC/DC Resonant LLC

Higher efficiency, higher power density, and higher component density have become common in power-supply designs and their applications. To achieve both higher switching frequencies and lower switching losses, many designs are turning to half- or full-bridge resonant LLC topologies. By using a resonant LLC tank, this effectively filters out harmonics resulting in low electro-magnetic emissions levels (EMI). It can also enable a high degree of integration in the magnetic parts, enabling the design of converters with higher efficiency and power density.
