Inductive Componets and Transformers

  To ensure the quality and to meet the special requirements of our own equipments on the inductive components, such as transformers and inductors. We established engineering capacity to develop inductors and transformers by our own. The technical experience and manufacturing scale have enabled us to serve our external customers too. Thus we also make and sell inductive components to our customers with the special design according to their requirements

  Our inductors have inductance range from several uH to hundreds mH with the working current up to tens amperes. They are made of different core materials of E type, I type, hollow type and toroid type. We make special transformer design for our customers too.

High Frequency Transformer

  To fulfill the demand from market such as switching mode power supply, UPS, DC/DC converters, we produce Industrial high-frequency transformers with core shape such as EE, EI, EC, ETD, EP, PQ. The transformers work from 30 kHz to 1mHz and deliver the power from 2W to 500W. According to working frequency and power density, they use core material such as ferrites, sendust, high flux, and MPP. We make transformers which comply with UL and VDE isolation requirements. These transformers have low loss at high frequency and high thermal stability. We patented our own winding schematic to reach low parasitic capacitance so that the product has good EMC features.

 Low  Frequency Transformer

These transformers work at 50 Hz. They are made of high quality silicon steel sheets. The silicon steel sheet with its high permeability works efficient at the low frequency. They cause low loss at 50 Hz, hence less temperature rise. We deliver transformers that match UL and VDE isolation requirements.

Different power ratings and shapes are available to satisfy our customer requirements.
The working voltage of such transformers complies with the requirements of ASIA, North America and Europe: 
400VAC 380VAC—240VAC—230VAC—220VAC—120VAC—110VAC—100VAC etc.

 Magnetic Material and Cores

  We worked together with several Universities and material research organizations in China to develop recipe of economical core material suited for the inductive characteristics of our own and customer demand. Our powder composition recipe takes geological advantage of the Chinese rare earth so that we can make low cost but high performance material for our customers. We compose our own powder and supervise the punch shaping and oven process at outsourcing factory to produce different kind of the soft magnetic cores:

Ferrites

  Ferrites are dense, homogenous ceramic structures made by mixing iron oxide with oxides or carbonates of one or more metals such as zinc, manganese, nickel or magnesium.  They are pressed, then fired in a kiln at 2000°F, and machined as needed to meet various operational requirements.  Ferrite parts can be easily and economically molded into much different geometry.   Many diversified materials are available, providing many choices of desirable electrical and mechanical properties.

Forms: Toroids, Pot Cores (Pot, RM, DS,RS, EP, PQ) Shapes (E,I,U,EEM,EFD, EC,ER,ETD,EER, Planar)

Powder Cores

Powder cores of alloy powders with distributed air gap possess many outstanding characteristics--high resistivity, low hysteresis and eddy current losses, and excellent inductance stability under both DC and AC conditions. Our powder composition recipe takes geological advantage of the Chinese rare earth so that we can make low cost high performance material for our customers.

Forms: Toroid, E Cores with air gap

Composition Cores

When developing and modifying the inductive components, the single characteristic cores cannot comprehensively meet the parameters required for some special functions. The newly developed composition cores have the features combining the unique outstanding of different core materials in one core to compensate each other to reach the multiple purposes.

Forms: Toroid, E Cores
