Calculation Formula

DC Voltage ≈ AC RMS Voltage * 0.9

Where:
AC RMS Voltage: The root mean square voltage of the AC source.
0.9: A typical efficiency factor representing the rectification and smoothing process.

Result

Estimated DC Voltage: 0.00 V

AC to DC voltage calculator Calculator Usage Guide

Learn how to use the AC to DC voltage calculator and its working principles

How to Use

  1. Enter the AC RMS voltage in volts (V).
  2. Enter the frequency of the AC source in Hertz (Hz). The standard value is 60 Hz for North America, and 50 Hz for many other parts of the world.
  3. Click the "Calculate" button to compute the estimated DC voltage.
  4. The calculator provides an approximate DC voltage equivalent after accounting for rectification and smoothing efficiency (typically around 90%).

Working Principle

This calculator provides an estimate of the DC voltage that would be produced by a full-wave rectifier circuit with smoothing capacitors when connected to an AC source. The actual DC output voltage can vary based on the rectifier's efficiency, the capacitance of the smoothing capacitor, and the load connected to the DC output.

The formula used is a simplified approximation: DC Voltage ≈ AC RMS Voltage * 0.9. This factor accounts for the typical voltage drop and conversion efficiency in a basic rectifier-smoothing circuit.
