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
