AI Technical Summary

Technical Problem

While ensuring power output performance, existing technologies struggle to achieve effective isolation between power outputs, especially in complex systems where there are deficiencies in isolated power supply design for level conversion and energy transfer between different functional modules.

Method used

Construct a power supply circuit including N power supply modules and N isolation modules. The first power output terminal is connected through the corresponding isolation module to achieve isolation between the power supply module and the second power output terminal. Voltage conversion and isolation are performed using transformers and power conversion circuits. The circuit design uses components such as DC-DC power chips and diodes.

Benefits of technology

While ensuring power output requirements, it achieves effective isolation between power outputs, enhances the circuit's anti-interference capability and voltage conversion accuracy, and reduces the size of the power supply circuit.
