Converter Duty Cycle Calculator

How Converter Duty Cycle works

This worksheet evaluates D = Vout ÷ Vin × 100. Converter Duty Cycle uses Output voltage, Input voltage to report Ideal duty cycle.

With the loaded values, ideal duty cycle evaluates to 41.67%. Hold the remaining entries steady while testing an uncertain input. For secondary current, use Transformer Current Calculator.

Inputs for Converter Duty Cycle

Output voltage and Input voltage belong to Converter Duty Cycle. Keep source units with output voltage.

Use the defaults to understand the output, then enter the real circuit or energy data.

Output voltage

Example entry: 5 V.

Input voltage

Example entry: 12 V.

Reading the Converter Duty Cycle result

This output represents Converter Duty Cycle.

Apply required margins only after identifying the correct equipment standard.

Measurement and units

Check component ratings, isolation requirements, temperature, waveform, and manufacturer limits. Check prefixes on output voltage.

Do not compare cases built from different unit prefixes or measurement locations.

Limits of this calculation

Topology and loss alter practical duty cycle. Required capacitance belongs in the separate Smoothing Capacitor worksheet.

Unlisted circuit behavior remains outside the computed result. Unentered effects remain outside Converter Duty Cycle.
