High Power Transformer Cores
|
High Power Transformer Cores:
Having high permeability, high saturation induction, low loss, and good temperature stability; widely used for the main transformer cores of uni-polar, push-pull or bi-polar type high frequency and high power inverter power supply and switched mode power supply.
Applications:
Inverter welding machines
X-ray and laser source power supplies
UPS and high frequency heating systems
Charging power supply
Electrolytic and plating power supply
Frequency conversion power supply
Characteristics:
High saturate induction—minimizing the volume of transformers
High permeability and low coercivity—increasing efficiency and reducing the exciting
power of transformers
Low core loss—minimizing the temperature rise of transformers
Excellent stability—serving from -55oC to 130oC for a long time
