Product Introduction
An internal flyback transformer is a type of flyback transformer that integrates electrical isolation, magnetic field energy storage, and multiple voltage outputs into a single high-frequency transformer. It achieves physical separation between the high-voltage and low-voltage sides while fulfilling three core functions: voltage conversion, electrical isolation, and energy storage and release. With its compact structure and high level of integration, it requires no additional energy storage inductor. Power conversion is realized by storing energy in the primary winding and releasing it through the secondary winding in a flyback manner, making it a core component in compact, low-power power supply equipment. The product complies with UL, CE, and CQC safety certifications, and features high insulation and flame-retardant ratings. Common model types include EC, EE, and PQ.
Product Features
The internal flyback transformer features a relatively simple product structure, low cost, easy implementation of multiple DC voltage outputs, compact size, and high operating efficiency. It supports fully automated production and offers good consistency, making it the best choice for cost-effective transformer solutions.
Application Fields
Internal flyback transformers are mainly used in:
FAQ
Q: How to control leakage inductance in flyback transformer design?
A: Keep leakage inductance within 2%–3% of the primary inductance during design.
Adopt the sandwich winding method during winding; ensure uniform and neat winding, and reduce the thickness of inter-layer insulation.
Avoid an excessively small number of turns during design. Too few turns will cause magnetic field dispersion, poor coupling and increased leakage inductance.
