AC to DC Conversion Formula:
| From: | To: |
AC to DC conversion is the process of converting alternating current (AC) to direct current (DC). This is commonly done using rectifiers in power supplies for electronic devices that require DC power.
The calculator uses the AC to DC conversion formula:
Where:
Explanation: The factor 0.636 represents the ratio of the average value to the peak value of a full-wave rectified sine wave (2/π ≈ 0.6366).
Details: Most electronic devices operate on DC power, while mains electricity is delivered as AC. Conversion is essential for powering everything from smartphones to computers and household appliances.
Tips: Enter AC voltage in volts (V). The value must be greater than 0. The calculator will provide the equivalent DC voltage after full-wave rectification.
Q1: Why is the conversion factor 0.636?
A: This factor (2/π) represents the ratio of the average value to the peak value of a full-wave rectified sine wave.
Q2: Does this calculation account for voltage drop in diodes?
A: No, this is a theoretical calculation. Real-world rectifiers have diode voltage drops (typically 0.7V for silicon diodes) that reduce the output voltage.
Q3: What's the difference between RMS and average voltage?
A: RMS (Root Mean Square) voltage is the equivalent DC voltage that would produce the same heating effect. Average voltage is the mathematical average of the voltage over one cycle.
Q4: When would I need to use this calculation?
A: This calculation is useful for designing power supplies, understanding rectifier circuits, and estimating DC output from AC input in basic electronic applications.
Q5: Are there different conversion factors for different wave forms?
A: Yes, the conversion factor varies depending on the waveform. This calculator assumes a perfect sine wave input.
