The large switching mode power supply transformer cores with low high frequency loss, high Bs and low Br so that to get the bigger △B. To manufacture the transformer cores with low Br and constant permeability by horizontal magnetic treatment for Nano-crystalline alloy core.
Application:
- Inverter welding machine power supply
- X-ray, laser, communication power supply
- UPS and high frequency induction heating power supply
- Charging power supply
- Electrolytic and electroplate power supply
- Frequency control of motor speed power supply
Characteristics:
• High Bs — Reducing volume and weight of the cores
- High permeability and low Coercive force — Improving the frequency and less exciting power for the transformer
- Low Br (Br < 0.2T) — Higher magnetic flux density and output power
- Low core loss — Lower temperature rising, higher efficiency of the transformer
- Excellent temperature stability — Keep stable working at -50’C-130’C for long time
Performance:
| Bs(T) | ≥1.2T |
| Br(T) | ≤0.15T |
| Loss (50KHz, 0.3T) | ≤30W/Kg |
| Loss (20KHz, 0.5T) | ≤25W/Kg |
| Initial permeability μ0 (Hm=0.08A/cm) | ≥30000 |
| Hc(A/m) | <2.0 |
| Tc(℃) | 570℃ |
