Application
● Mid-frequency power transformer core, distribution transformer core
● Toroidal uncut cores for smooth filtered output inductors and differential mode input inductors for switching power supplies
● Noise suppression in car stereos, toroidal uncut cores for car navigation system chokes
● Ring-cut cores for PFC power factor correction in air conditioning and plasma TVs
● High frequency rectangular cut cores for output inductors and transformers for switching power supplies, uninterruptible power supplies, etc.
● Toroidal, uncut cores for IGBTs, MOSFETs and GTOs pulse transformers
● High power density variable speed motors, stators and rotors for generators
Features
● Highest saturation magnetic induction among amorphous alloys-reduce components size
● Low coercivity- Improve components efficiency
● Variable Magnetic flux rate – By different core heat treatment processes to meet the requirements of different applications
● Good temperature stability- Can work at -55°C -130°C for long periods of time
● Cores used in transformers are 75% more energy efficient than S9 silicon steel cores in terms of no-load losses and 25% more energy °C efficient in terms of load losses
● Short strip production process and low production cost (see Fig. 1.1)
● The strip has a special microstructure which determines its excellent magnetic properties (Fig. 1.2) and performance stability.
● The composition and process parameters of the strip can be quickly adjusted to meet different usage requirements.
● For new energy solar grid-connected inverters
