Description
A half-bridge LLC resonant converter with Zero Voltage Switching (ZVS) and Pulse Frequency Modulation (PFM) is a lucrative topology for DC/DC conversion. A Digital Signal Controller (DSC) provides component cost reduction, flexible design, and the ability to monitor and process the system conditions to achieve greater stability. The dynamics of the LLC resonant converter are investigated using the small signal modeling technique based on Extended Describing Functions (EDF) methodology. Also, a comprehensive description of the design for the compensator for control of the LLC converter is presented.
