Superworld Electronics designs High-Frequency Transformers for high-efficiency SMPS, telecom, and renewable applications.
Using ANSYS electromagnetic simulation (>90% correlation), we accurately predict loss, EMI, and thermal behavior before production.With strong ferrite know-how and automated winding, we ensure tight tolerance, low loss, and stable high-power performance.
By leveraging ANSYS simulation, we collaborate closely with customers, enabling faster design understanding, quick iteration cycles, shorter waiting time, and fast support for each use case.
High-Frequency Transformer Fundamentals
Serve two main purposes:
1. Energy transfer between primary and secondary circuits.
2. Electrical isolation for safety and noise reduction.
Electromagnetic Principle
When AC flows through the primary winding, it creates magnetic flux in the ferrite core.
This flux induces voltage in the secondary winding, as defined by:
