Use our Bridge Rectifier Calculator to quickly determine the average DC output voltage and ripple frequency from your AC input. Account for transformer secondary voltage, AC frequency, and individual diode forward voltage drops for precise circuit design.
Formula:
The calculations performed by this tool are based on the following fundamental formulas:
- Peak AC Voltage (Vpeak): Vpeak = VRMS × √2
- Average DC Output Voltage (VDC_avg): VDC_avg = (2 × Vpeak / π) - (2 × Vdiode_drop)
- Ripple Frequency (fripple): fripple = 2 × finput
Where:
- VRMS = RMS AC Input Voltage (from transformer secondary)
- Vpeak = Peak AC Voltage
- Vdiode_drop = Forward Voltage Drop across a single diode (e.g., 0.7V for silicon)
- π ≈ 3.14159
- finput = Input AC Frequency
- fripple = Output Ripple Frequency
