📊 KATOY Toroidal Transformers
A toroidal transformer is a type of electrical transformer with a ring-shaped (doughnut-shaped) magnetic core, usually made of ferrite or laminated silicon steel, around which the wire windings are wrapped.
Katoy can manufacturer toroidal transformers to any specification required for your application.
🔄 How Toroidal Transformers Work
Just like other transformers, a toroidal transformer transfers electrical energy between circuits using electromagnetic induction. The primary winding creates a magnetic field in the core, which induces voltage in the secondary winding.
🌀 Toroid Shape Benefits
The toroidal (circular) core gives this transformer some distinct advantages:
✅ Advantages
- High Efficiency
- Minimal magnetic flux leakage due to the closed-loop shape.
- Higher power transfer efficiency.
- Low Electromagnetic Interference (EMI)
- Magnetic field is well-contained, which reduces noise and interference to nearby electronics.
- Compact Size & Light Weight
- For the same power rating, toroidal transformers are generally smaller and lighter than traditional laminated-core transformers.
- Quiet Operation
- Less mechanical hum and vibration.
- Easy to Mount
- Usually secured with a single bolt through the center hole.
📦 Common Uses
- Audio equipment (due to low noise)
- Medical devices
- Power supplies in computers and electronics
- Industrial control systems
- Solar inverters and UPS systems
