More Information
Summary:The invention relates to a novel full-bridge LLC no-load and loaded voltage control method. A control circuit adopted in the method includes a switching network, a resonant network and a rectifying network; according to the switching network, switch tubes Q1, Q2, Q3 and Q4 are utilized to form a single-phase full-bridge controllable inverter structure; AND according to the resonant network, an LLC resonant cavity is adopted. In a full load arrange, the invention provides a complete set of voltage control scheme which enables an LLC to realize output voltage control in no-load and heavy-loaded conditions.
