When winding a toroidal core to achieve approximately 1 volt per turn, it is necessary to calculate the relationship between the number of turns and the voltage based on transformer principles.
When winding a toroidal core to achieve approximately 1 volt per turn, it’s necessary to calculate the relationship between the number of turns and voltage based on transformer principles. The specific procedure is as follows:
Winding Steps
Determine parameters
Calculate the number of primary winding turns based on the required voltage and power. For example: If the target voltage is 24V, the primary winding should have approximately 2,400 turns (the exact number may need to be adjusted according to the actual current and wire specifications).
Winding Method
**Layer Winding Method:** On the inner side of the toroidal core, use tight layer winding to prevent wire crossings; maintain a 1–3 mm gap on the outer side (adjustable based on wire diameter and power requirements).
Insulation Treatment: Secure the winding with insulating tape before and after wrapping, and add green shell paper for isolation at the lead-out wire locations.
Test Verification
After winding is complete, test the output voltage using an AC power source, and adjust the number of turns or replace the wire gauge as needed.
Important Notes
The actual voltage is influenced by factors such as wire resistance and core permeability, and must be calculated using the appropriate formula (V = N × E / R, where N is the number of turns, E is the induced electromotive force, and R is the total resistance).
Ring transformers are highly efficient with minimal magnetic leakage, making them suitable for high-frequency applications—but they require high precision in winding.
