AC to DC Voltage Conversion Formula:
From: | To: |
The conversion from AC (Alternating Current) voltage to DC (Direct Current) voltage is a fundamental calculation in electronics and electrical engineering. The RMS AC voltage is multiplied by the square root of 2 (≈1.4142) to obtain the equivalent DC voltage.
The calculator uses the AC to DC conversion formula:
Where:
Explanation: This conversion assumes ideal full-wave rectification of a pure sine wave with no losses.
Details: Understanding AC to DC conversion is essential for designing power supplies, battery chargers, and any electronic device that requires DC power from an AC source.
Tips: Enter the AC RMS voltage in volts. The calculator will compute the equivalent DC voltage after full-wave rectification.
Q1: Why multiply by √2?
A: The √2 factor converts RMS voltage to peak voltage, which is the maximum DC voltage you'd get from perfect rectification.
Q2: Does wire size affect the calculation?
A: No, wire size is irrelevant for this basic voltage conversion calculation, though it matters for current capacity in actual circuits.
Q3: What about half-wave rectification?
A: Half-wave rectification would produce different results, with average DC voltage being about 0.45 times the RMS AC voltage.
Q4: Are there real-world losses?
A: Yes, actual circuits have diode voltage drops, transformer losses, and other factors that reduce the output voltage.
Q5: What's the difference between RMS and peak voltage?
A: RMS (Root Mean Square) is the effective voltage, while peak voltage is the maximum instantaneous voltage in an AC waveform.
