Other Details

We design and manufacture SMPS Transformer that is an electronic power supply unit that incorporates a switching regulator in order to provide the required output voltage. These can be narrowed down to three basic circuit configurations Buck, Boost and fly back. We also offer unipolar and bipolar (push-pull) versions. The switch mode transformer is used in conjunction with the switching regulator to form a switch mode power supply. Switch mode power transformers are used extensively in electronic applications, usually within a switch mode power supply. SMPS transformers run at high frequency.

Features: 

• Most of the cost savings (and space savings) in off-line power supplies result from the smaller size of high frequency transformer compared to the 50/60 Hz transformers formerly used

• The terminal voltage of a transformer is proportional to the product of the core area, magnetic flux, and frequency. By using a much higher frequency, the core area (and so the mass of the core) can be greatly reduced

• Core losses increase at higher frequencies. Cores use ferrite material which has a low loss at the high frequencies and high flux densities used
