Use one consistent electrical operating case for all fields.

V

Enter ac rms voltage in V.

Enter rectifier factor in the displayed unit.

How Rectifier DC Output works

The displayed equation is Vdc ≈ Vrms × rectifier factor. Rectifier DC Output uses AC RMS voltage, Rectifier factor to report Average DC output.

In the loaded Rectifier DC Output case, average DC output equals 10.80 V. Label alternate cases before adjusting an assumption.

Inputs for Rectifier DC Output

AC RMS voltage and Rectifier factor belong to Rectifier DC Output. Keep source units with ac rms voltage.

The initial entries illustrate operation only. Use current records, readings, or nameplate values for planning.

AC RMS voltage
Example entry: 12 V.
Rectifier factor
Example entry: 0.9.

For Rectifier DC Output, record aC RMS voltage, rectifier factor. Record AC RMS voltage state for Rectifier DC Output. Keep average DC output unrounded.

Classify AC RMS voltage as test, operating, rated, or limiting. Rectifier DC Output accepts one entry. Separate average DC output cases when aC RMS voltage varies.

Reading the Rectifier DC Output result

This output represents Rectifier DC Output.

Use the result as a planning quantity before checking available ratings and protective requirements.

Use Average DC output to the average DC output calculation. Compare it with voltage stress, current stress, loss, ripple, regulation, and thermal capacity. Average DC output does not override another Transformers and Power Supplies limit.

Measurement and units

Check component ratings, isolation requirements, temperature, waveform, and manufacturer limits. Check prefixes on ac rms voltage. Use Transformer Copper Loss Calculator to a separate copper loss calculation.

Reconcile prefixes and units before comparing outputs.

For Rectifier DC Output, source AC RMS voltage from nameplate data, winding measurements, oscilloscope traces, and load tests. Record line voltage, frequency, waveform, load level, and component temperature. Rectifier factor needs matching conditions.

Convert AC RMS voltage for Rectifier DC Output. Store original and converted aC RMS voltage values for Rectifier DC Output. Prefix errors alter average DC output.

Limits of this calculation

Diode drops and load current change output.

This worksheet does not model every behavior in the surrounding system. Unentered effects remain outside Rectifier DC Output.

Evaluate leakage inductance, parasitic capacitance, core saturation, switching transients, and cooling separately. In Rectifier DC Output, represent each effect through AC RMS voltage. Document aC RMS voltage allowances.

A useful Rectifier DC Output comparison

Save the initial average DC output before adjusting aC RMS voltage. A low and high case is more informative than adding an unexplained safety factor after the calculation.

Document the alternate ac rms voltage source.

Suppose AC RMS voltage is measured as 10.2 V instead of the example value 12 V. With rectifier factor retained, average DC output becomes 9.18 V rather than 10.80 V. Store both Rectifier DC Output cases if either input is plausible; averaging them can conceal a limiting condition.

Records for Rectifier DC Output

Record source and operating details for ac rms voltage.

Retain raw average dc output beside its selected rating.
