Abstract
The present disclosure provides a power conversion device including an input end having positive and negative input terminals, two bridge arms, two transformers and an output capacitor. Each bridge arm is connected to the input end in parallel, and includes three switches coupled in series. Two terminals of one switch are electrically connected to the positive input terminal and a primary node respectively. Two terminals of another switch are electrically connected to the negative input terminal and a secondary node respectively. Each transformer includes primary and secondary windings coupled to each other. Two primary windings are serially coupled between two primary nodes. Two secondary windings are serially coupled between two secondary nodes. Two terminals of the output capacitor are electrically connected to output positive and negative terminals respectively. The positive output terminal is coupled between the secondary windings, and the negative output terminal is coupled to the negative input terminal.
