Product Description
NANOCRYSTALLINE TRANSFORMER CORE USED IN INVERTER WELDING MACHINE POWER SUPPLY
Inverter magnetic core is a very key component in the inverter, it plays an important role in the process of energy conversion and transmission.The common inverter core material is nanocrystalline. Nanocrystalline magnetic core has many advantages, such as high saturation magnetic induction, low loss, high permeability and so on.The high saturation magnetic induction strength means that it can withstand a large magnetic field strength without easy saturation, which can improve the power output capacity of the inverter. The low loss feature helps to reduce the loss of energy in the core, improve the efficiency of the inverter, reduce operating costs and heat. The high permeability allows the core to conduct and transform the magnetic field more effectively, thereby optimizing the performance of the inverter.The selection of the appropriate inverter core needs to consider the power requirements of the inverter, working frequency, efficiency requirements, cost and other factors. Different types and performance of the magnetic core will directly affect the performance, size and cost of the inverter.
Performanc
*High Bs - Reducing volume and weight of the cores
*High permeability and low Coercive force --Higher efficiency and less excited power of transformer
*Low Br (Br≤0.2T) - Higher magnetic flux density and output power
*Low core loss - Lower temperature rising,higher efficiency of the transformer
*Keep stable working at -45ºC ~ 130 ºC for long time.
Applications
*Inverter Welding machine power supply
*X-ray, laser, communication power supply
*UPS and high frequency induction heating power supply
*Frequency control of motor speed power supply
*Charging power supply
*UPS
*High Saturation magnetic induction - reduce transformer volume
