AI Technical Summary

Technical Problem

In existing electrical systems for new energy vehicles, independent transformer or inductor structures lead to redundant setups of magnetic circuits, windings, heat sinks, and EMI shielding shells, resulting in increased system size and weight, making it difficult to meet miniaturization and lightweight requirements.

Method used

The DC conversion transformer, PFC boost inductor, and OBC resonant inductor are integrated on the base and positioned by positioning slots, reducing the redundant setup of magnetic circuits, windings, heat sinks, and EMI shielding shells. Heat sinks and pads are used for efficient heat dissipation.

Benefits of technology

It significantly reduces the size and weight of the system, improves the integration of components and heat dissipation efficiency, meets the requirements of new energy vehicles for miniaturization and lightweighting, and ensures the stability and reliability of electromagnetic components.
