Yu Yang Magnetic Co., LTD. (YET) is a leading electrical transformer manufacturer, specializing in the design and production of both low frequency transformers and high frequency transformers for industrial, automotive, energy, and communication applications. Our electrical transformers feature excellent thermal stability, low power loss, and robust mechanical strength — all made possible by our vertically integrated core processing, precision winding, and vacuum encapsulation capabilities.

Versatile Electrical Transformers for Modern Power Systems

At YET, our transformer portfolio covers a wide operating spectrum — from power frequency transformers (50/60Hz) used in conventional AC power systems, to high-frequency transformers designed for switch-mode power supplies, inverters, and DC-DC conversion circuits.

Our products are engineered using:

• Laminated silicon steel cores for low-frequency, high-efficiency AC power conversion

• Ferrite cores for compact, high-frequency switching circuits

• Vacuum potting and encapsulation for enhanced insulation and moisture resistance

• Custom winding topologies for optimal magnetic performance and space-saving integration
  
  

Our Electrical Transformer Categories

Mains Transformer (Low Frequency / Power Frequency Transformer)

Built using laminated silicon steel cores, our mains transformers operate reliably at 50/60Hz and are suitable for AC-DC power supply isolation, step-up/step-down voltage regulation, and industrial motor control systems.

• Low no-load loss

• High magnetic permeability

• Stable operation under fluctuating grid conditions

• Complies with RoHS & IEC safety standards

High Frequency Transformer

Our high-frequency transformers are compact, lightweight, and optimized for energy-efficient performance in power electronics systems.

• Operating frequency up to 1MHz

• Suitable for SMPS, inverters, battery chargers, and telecom power modules

• Designed with ferrite cores (PC40, PC44, etc.) for minimal core loss

• Shielded designs available for EMI-sensitive applications

Models include EFD, ER, PQ, RM, and custom SMD/DIP variants.

Application Fields

YET’s electrical transformers are used across a wide range of industries:

• Industrial Control Systems: motor drivers, automation power supplies, signal isolators

• Automotive Electronics: OBC, DC-DC converters, e-motor controllers

• Renewable Energy: PV inverters, wind power converters, ESS (Energy Storage Systems)

• Consumer Electronics: chargers, LED drivers, smart appliances

• Telecom & Networking: PoE, base stations, telecom-grade rectifiers

Customization Capabilities

With an advanced design team and magnetic simulation tools (Maxwell, HFSS, ANSYS), YET offers complete OEM/ODM services for:

• Special voltage/current ratings

• Multi-winding isolation
