In the hope of sharing details regarding digital components, Easybom, an online search engine for the digital element industry, has actually collected the info which aids you to differentiate pulse transformers from high-frequency transformers.
A pulse transformer is a sort of broadband transformer. Nonlinear distortion is an extremely substantial sign for transformers utilized for communication. Consequently, it calls for that the transformer ought to operate at the initial permeability of the magnetic core, to ensure that even the transformer with little power such as the input transformer must remain in a big shape. Decreasing the loss is another issue for the transformer besides the frequency qualities.
Comparison of pulse transformer and general transformer carried out by Easybom:
The standard concepts of all pulse transformers are the same as basic transformers (such as audio transformers, power transformers, and so on), however, the magnetization process of the magnetic core is various as follows:
1. The pulse transformer is a transformer that works in a short-term state. To put it simply, the pulse process happens in a short amount of time, as well as it is a square wave with a smooth top. The general transformers operate in continuous and changeless magnetization. The rotating signal modifications according to a sine wave.
2. The pulse signal is a recurring cycle with a certain period, as well as just positive or adverse voltage, while the rotating signal is continually repeated, with both favorable and adverse voltage values.
3. No distortion of the pulse transformer require when the waveform is transferred, as well as the edge of the waveform is required and the upper fall should be as low as possible. Nevertheless, these 2 indications are inconsistent.
The contrast of high-frequency transformer and pulse transformer carried out by Easybom:
1. Different in nature
High-frequency transformer: A power transformer with a working regularity which surpasses the intermediate frequency (10kHz).
Pulse transformer: a transformer with wide regularity
2. Difference in operation
High-frequency transformer: It mostly uses as a high-frequency switching power transformer in high-frequency switching over the power supply. As well as also used a high-frequency inversion power transformer in high-frequency inversion power supply as well as high-frequency inversion welding equipment.
Pulse transformer: It is extensively utilized in different applications. Such as radar as well as the conversion of modern technology, the matching of lots resistance and feeder particular resistance. The rise and lower in pulse voltage, and the isolation of the secondary circuit.
3. Distinction in principle
High-frequency transformer: In the switching power supply, the high-frequency transfers a high-frequency pulse square wave signal. Because of this, the leak inductance. As well as dispersed capacitance. Must decrease to a marginal value when the high-frequency transformer is under the layout. The leak inductance and dispersed capacitance will certainly generate a rising in current, peak voltage. Leading oscillation in the short-term procedure of transmission, which causes a boosted loss.
As per the advice provided by Easybom, you can clearly differentiate the differences between the high-frequency transformer and pulse transformer. Also, choose which one is more appropriate for you.
