The core innovation of the SST solution lies in achieving a leapfrog upgrade in insulation and moisture resistance without compromising the original performance of the magnetic core. Conventional insulation solutions often result in disordered magnetic field distribution and reduced leakage inductance control accuracy of the magnetic core due to inappropriate material selection or redundant structural design. This solution addresses this industry pain point at its root through two key technical optimizations:

Lightweight Design of Boss Structure: Abandoning the structural redundancy caused by the traditional thick insulating layer, a boss structure precisely matching the contour of the magnetic core is adopted. While ensuring the insulation gap, it minimizes obstruction to the magnetic field path and guarantees that the magnetic field distribution conforms to the original design trajectory.

Matching of Low Permeability Characteristics of Silicone Rubber: Carefully selected low-permeability silicone rubber materials are optimally matched with the magnetic core and surrounding components in terms of permeability, avoiding magnetic field refraction and scattering caused by differences in material magnetic properties, and ensuring magnetic field stability at the material level.

Through dual optimizations of structure and material, the solution has achieved a core indicator of leakage inductance control accuracy error ≤ ±2%, fully retaining the magnetic performance of the original design:

Undisturbed Magnetic Field Distribution: The combination of the boss structure and low-permeability materials ensures that the magnetic field lines of the magnetic core are always conducted along the designed path during operation, without abnormalities such as deviation or leakage.

Guaranteed Performance Consistency: After multiple rounds of high and low temperature and damp heat environmental tests, the fluctuation range of the magnetic core leakage inductance value is strictly controlled within ±2%, which is completely consistent with the performance data of the original design without insulation protection. This completely breaks the traditional perception that “insulation upgrade inevitably reduces magnetic performance”.

Compared with conventional insulation solutions, the SST solution unifies two core values:

Solving Insulation Protection Pain Points: Leveraging the moisture-proof and insulating properties of silicone rubber materials combined with the precise protection of the boss structure, it effectively resists the erosion of the magnetic core by harsh environments and meets high-level electrical safety requirements.

Avoiding Magnetic Performance Deviation Risks: Discarding the thick structures and high-permeability materials that affect the magnetic field in traditional solutions, it ensures no reduction in the leakage inductance control accuracy of the magnetic core while upgrading protection, realizing the dual guarantee of “upgraded protection and unchanged performance”.
