Basic Characteristics of an Optimal Trajectory Controlled LLC Resonant DC-DC Converter at Continuous Current Mode

This work investigates the application of optimal trajectory control for an LLC resonant DC-DC converter. The operating frequency is higher than that of the series resonant circuit and the rectifier input current is continuous. Based on the results of an existing state-space analysis, the output and control characteristics are obtained. Important properties of the LLC resonant DC-DC converter are discussed.
