LLC multi-level LLC resonant converter and electronic device

摘要

An LLC resonant converter and electronic device are disclosed. The LLC resonant converter of the present invention includes multiple input transformers and first and second converter units connected to the primary side of the multiple input transformer, an input voltage unit, a first balanced capacitor, and an output connected to the secondary side of the multiple input transformer. It consists of wealth. Each converter unit includes a first part in which one switch and one resonant capacitor are connected in series, and a second part in which other switches and other resonant capacitors are connected in series, and includes first parts, second parts, and transformers. One input side winding is connected in parallel, each switch is connected, each resonant capacitor is connected, and the first balanced capacitor is connected to a node between switches of each converter unit.
