Description

Product Features

The switching power supply transformer iron-based nanocrystalline toroidal core features better performance characteristics. First, it has extremely low iron losses and the iron loss has little change in a wide temperature range(-25℃ to 120℃). The factor of temperature independence ensures reliable efficiency across changing conditions without the use of temperature-compensation circuits and with reduced power supply unreliability.

Second, because of its high saturation magnetic flux density of 1.2T, power engineers can have lower operating frequencies, between 20kHz and 50kHz. This not only reduces the stress on power semiconductor devices, but the cost of EMI filtering components is also lowered, thus making the overall power supply design economical.

Third, the core has a high enough magnetic permeability that varies relatively little with changes in the magnetization field and frequency. That stability ensures inductance levels with values that can be anticipated and performance uniformly under different working conditions, making design and reliability of the power supply easier.

Product Applications

The Switching power supply transformer iron-based nanocrystalline toroidal core is an ideal choice for the main transformers of the switching power supplies. In today’s electronic devices, e.g., laptops, smartphones, and servers, the need for efficient and compact power supplies is extremely high. The low core loss and good magnetic performance of this core make the main transformer operate with minimum energy dissipation, significantly increasing the power conversion efficiency of the switching power supply. Its steady operation in broad temperature range ensures reliable operation under harsh conditions. Moreover, the ability to handle lower frequencies reduces the stress of power semiconductor devices and components of EMI filters and results in a cheaper and more reliable power supply design. Therefore, it has turned into a vital component of high-performance switching power supply main transformers.

In short, power transformer iron-based nanocrystalline toroidal cores for switching power supply is a low energy consumption stable magnetic component. Its very low core loss, good operating performance with a wide operating temperature range of – 25°C to 120°C, high saturation magnetic flux density, and consistent magnetic permeability make it exceptional. These attributes allow power engineers to design the switching power supply main transformers optimally in order to reduce costs of semiconductor devices and EMI filtering as well as increase conversion efficiency. Be it consumer electronics or industrial machinery, this core ensures a steady power output and plays a crucial role in today’s power supply systems.
