Product Overview

The ETD34 LLC Resonant Converter Transformer is designed for high-efficiency resonant power conversion systems requiring stable high-frequency operation, low switching loss, and reliable electrical isolation.

Built with an ETD34 ferrite core structure, the transformer provides optimized magnetic coupling, improved thermal performance, and high power density for LLC resonant converter topologies.

Its resonant-optimized winding design supports efficient soft-switching operation, helping reduce switching stress and improve overall power conversion efficiency in modern AC-DC SMPS systems.

The ETD34 series is widely used in industrial power supplies, server power systems, communication equipment, and high-efficiency switching power applications.

Customized turns ratios, resonant parameters, insulation systems, and winding structures are available according to application requirements.
