Understanding HFCT
HFCTs are similar in principle to conventional low-frequency transformers but have specific design considerations to handle high-frequency signals. They typically feature:
- High-permeability core materials: These materials, such as ferrite or powdered iron, have high magnetic permeability, allowing for efficient flux transfer at high frequencies.
- Multiple windings: HFCTs often have multiple windings with a primary winding connected to the high-frequency current source and one or more secondary windings connected to the load or measurement devices.
- Low inductance: The inductance of HFCTs is designed to be low to minimize energy storage and reduce phase shifts at high frequencies.
- Compact size: HFCTs are typically smaller in size than low-frequency transformers due to the use of high-frequency core materials and specialized winding techniques.
