A Mathematical Guideline for Designing an AC-DC LLC ...
gansystems.comA. LLC Resonant Converter Voltage Gain Review The half-bridge LLC resonant converter prototype is shown in Fig. 1. The operating frequency range of the LLC PFC is defined as fp ≤ fs ≤ fr, where below-resonance operation is preferred to ensure the inductive impedance characteristics of the LLC resonant tank, so that the soft

www.onsemi.comHigh Performance Resonant Mode Controller with Integrated High-Voltage Drivers The NCP1397 is a high performance controller that can be utilized in half bridge resonant topologies such as series resonant, parallel resonant and LLC resonant converters. It integrates 600 V gate drivers, simplifying layout and reducing external component count.
ON Semiconductor Is Now
www.onsemi.comLLC resonant half bridge converters are widely used in consumer electronics, like powering the display panel of LCD TV. However, the operating principles of a LLC resonant half bridge converter are far from apparent and intuitive [1]. This application note focuses on the intuitive and conceptual understanding of a LLC resonant converter.
