Full-Wave Bridge Rectifier Designer
Estimate rectified DC voltage, ripple frequency, reservoir capacitance, and diode stress for a low-voltage supply.
Answer first
How do I use a full wave bridge rectifier calculator?
Estimate rectified DC voltage, ripple frequency, reservoir capacitance, and diode stress for a low-voltage supply. Enter the known values and inspect the result immediately. For example, Enter the transformer secondary, load current, diode drop, capacitance, and mains frequency to estimate DC output and ripple. Use the output to check your reasoning or shortlist a design, then verify the units, assumptions, and real-world limits that apply.
Set your supply targets
Trace an operating phase
The highlighted path carries conventional current. Values follow your inputs.
During an A-positive charging pulse, D1 and D4 conduct. The reservoir and load receive the same DC polarity.
Constant-current, small-ripple estimate. Diodes conduct in charging pulses near each peak; source impedance and surge current are not modeled.
Equations and model scope
This is a low-voltage, isolated AC source model with constant load current. The reservoir approximation is most useful when ripple is small compared with the rectified peak. Transformer impedance and diode charging-current peaks are excluded.

Worked approach
Try a concrete set of values
Enter the transformer secondary, load current, diode drop, capacitance, and mains frequency to estimate DC output and ripple. Change one input at a time, confirm the units, and compare the result with an independent calculation or relevant datasheet.

Questions engineers ask
What should I enter in the Full-Wave Bridge Rectifier Designer?
Use known values in the units shown beside each field. Keep every input within a realistic range and convert units before comparing the result with another source.
Can I use the Full-Wave Bridge Rectifier Designer result directly?
