Flyback Transformer Calculator
Flyback Transformer reports ideal secondary voltage from one operating case.
Enter values for ideal secondary voltage
Use one consistent electrical operating case for all fields.
How Flyback Transformer works
The calculation starts with Vs ≈ Vp × turns-duty factor. Flyback Transformer uses Primary voltage, Turns-duty factor to report Ideal secondary voltage.
With the loaded values, ideal secondary voltage evaluates to 76.80 V. Preserve the baseline before changing a value.
Inputs for Flyback Transformer
Primary voltage and Turns-duty factor belong to Flyback Transformer. Keep source units with primary voltage.
The preset case is instructional rather than prescriptive. Enter the applicable electrical data. Compare this result with Rectifier DC Output Calculator when average DC output is also needed.
- Primary voltage
- Example entry: 24 V.
- Turns-duty factor
- Example entry: 3.2.

Finish the selection with standard sizes, operating limits, and transient review.
Measurement and units
Check component ratings, isolation requirements, temperature, waveform, and manufacturer limits. Check prefixes on primary voltage. For transformer efficiency, use Transformer Efficiency Calculator.
Use the same unit basis and observation location in alternate cases.
Limits of this calculation
Leakage inductance and switching loss require a detailed design.
A complete system can contain effects that this equation does not represent. Unentered effects remain outside Flyback Transformer. Use Buck Converter Calculator.
Questions about Flyback Transformer
