Any switched-mode power supply that gets its power from an AC power line (called an "off-line" converter) requires a transformer for galvanic isolation. Some DC-to-DC converters may also include a transformer, although isolation may not be critical in these cases. SMPS transformers run at high frequency. Most of the cost savings (and space savings) in off-line power supplies result from the smaller size of the high frequency transformer compared to the 50/60 Hz transformers formerly used.
Cores generally use ferrite material which has a low loss at the high frequencies and high flux densities used. The laminated iron cores of lower-frequency (<400 Hz) transformers would be unacceptably lossy at switching frequencies of a few kilohertz. Also, more energy is lost during transitions of the switching semiconductor at higher frequencies. Furthermore, more attention to the physical layout of the circuit board is required as parasitic become more significant, and the amount of electromagnetic interference will be more pronounced.
We offer SMPS Transformers in various types & specifications as per customer design as under :
EE series EF Series
ETD series EI Series
PQ series EFD series
Transformers for use at power or audio frequencies typically have cores made of high permeability silicon steel. The steel has a permeability many times that of free space and the core thus serves to greatly reduce the magnetizing current and confine the flux to a path which closely couples the windings.
One common design of laminated core is made from interleaved stacks of E-shaped steel sheets capped with I-shaped pieces, leading to its name of 'E-I transformer'. Such a design tends to exhibit more losses, but is very economical to manufacture.
Distribution transformers can achieve low no-load losses by using cores made with low-loss high-permeability silicon steel or amorphous (non-crystalline) metal alloy. The higher initial cost of the core material is offset over the life of the transformer by its lower losses at light load.
The Toroidal Transformers are manufactured by using High Quality Grade CRGO and CRNGO cores as per customers specification. Toroidal Transformers work more efficiently with low Stray Magnetic field.
We offer Common mode choke as per customer design and specification in following types :
UU Series EE Series
UT Series ET Series
Inductor are manufactured with Drum core, Rod core in various sizes as per customers specification
Impedance Transformers :
Pulse Transformers : A “pulse transformer” is any transformer capable of transmitting voltage pulses (often rectangular) with adequate signal fidelity. Requirements like high-permeability core, low leakage inductance, low inter-winding capacitance etc. are common also to the power transformers in several switched-mode power supplies. Therefore, extremely high power transformers (rating MW or even TW) can be referred to as “pulse transformers
Potted Transformers :
Air core Inductor : We also offer to our customers Air core coil describes an inductor that does not use a magnetic core . The coils wound on plastic, ceramic, or other nonmagnetic forms, as well as those that have only air inside the windings. Air core coils have lower inductance than ferromagnetic core coils, but are often used at high frequencies because they are free from energy losses called core losses that occur in ferromagnetic cores, which increase with frequency
