How to use the bridge rectifier output calculator
Estimate the peak and average DC output of a bridge rectifier after diode drops. Enter ac input rms voltage, voltage drop per diode in the fields above; the peak output after bridge, average dc output (approx.) are computed instantly and plotted on the chart so you can see how the answer changes.
Common searches this calculator answers include “bridge rectifier output”, “diode bridge voltage”, “rectified DC voltage”, “calculate bridge rectifier output”, “find peak output after bridge”.
Formula
Variables
- Vrms — AC input RMS voltage (V)
- Vd — Voltage drop per diode (V)
Worked example
With ac input rms voltage = 12 V, voltage drop per diode = 0.7 V, the calculator gives peak output after bridge ≈ 15.57056 V; average dc output (approx.) ≈ 9.912528 V.
Frequently asked questions
What is the bridge rectifier output calculator used for?
Estimate the peak and average DC output of a bridge rectifier after diode drops. It helps with questions such as “bridge rectifier output”, “diode bridge voltage”, “rectified DC voltage”.
What is the formula for the bridge rectifier output calculation?
Peak output after bridge (V) = Vrms × √(2)-2 × Vd. Average DC output (approx.) (V) = [Peak output after bridge] × 2 / π. Here Vrms is ac input rms voltage (V), Vd is voltage drop per diode (V).
What inputs do I need for the bridge rectifier output calculator?
You need ac input rms voltage in V, voltage drop per diode in V. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use the bridge rectifier output calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the bridge rectifier output result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
