2. Marking signal direction: On the basis of the actual circuit diagram, the signal transmission direction is marked by adding symbols such as arrows, which is convenient for readers to understand the working principle of the circuit.
3. Fuzzy key part: In the actual circuit diagram, the connection between the input and output of the bidirectional converter is fuzzy to highlight its bidirectional transmission characteristics. You can blur it with dashed lines or gray fills.
4. Add text description: On the basis of fuzzy diagram, appropriate text description can be added to introduce the working principle and practical application scenarios of bidirectional converter to help readers better understand the content of the paper.
