Rectifier Voltage Calculator
Easily calculate DC output voltage from half-wave, full-wave, and bridge rectifiers. Includes ripple, diode drop, and capacitor filter effects.
bridge rectifier voltage calculator
A rectifier voltage calculator is a device that changes the AC input into DC output voltage. To design half-wave and full-wave rectifiers, on average, you can calculate DC voltage using diode drops and half-wave and full-wave rectifier formulae, considering the ripple. In practice, you can use it.
Formula & Table Summary:
Half-Wave: Vdc = Vm/π - Vd
Full-Wave: Vdc = 2Vm/π - 2Vd
Bridge: Vdc = 2Vm/π - 2Vd
Ripple: Vr = I/(fC)

The Rectifier Voltage Calculator assists you in finding out the DC rectified voltage at an AC supply instantly with a half-wave rectifier, full-wave rectifier, and bridge rectifier. Rectifiers transform the alternating current (AC) to direct current (DC) by not passing all, but only the positive half-cycles/both halves of the input waveform. Diode voltage drop, RMS input, and filtering capacitors are the factors that affect the final DC voltage. Rectifier voltage calculation is applied in power supply, converters, chargers, and electronic circuit design by engineers and students. With the correct formulas, it is easy to compute the average DC output, peak voltage, and ripple voltage correctly based on the type of rectifier used.

| Full-Wave | 20 V | 1.4 V | 11.33 V | 0.6 V |
| Bridge | 20 V | 1.4 V | 11.33 V | 0.6 V |
Frequently Asked Questions - Rectifier Voltage Calculator:
What is a rectifier voltage calculator?
It is a tool to calculate DC output voltage from AC input using half-wave, full-wave, or bridge rectifiers.
How do you calculate half-wave rectifier output?
The average DC voltage is Vdc = Vm/π - Vd, where Vm is peak AC and Vd is diode drop.
What is the formula for full-wave rectifier DC voltage?
Vdc = (2Vm/π) - 2Vd.
Does a bridge rectifier have the same output as a full-wave?
Yes, both provide the same average DC output, but bridge uses four diodes.
What role does diode drop play in rectifier output?
Diode forward voltage drop reduces the DC output slightly.
What is ripple voltage in rectifiers?
Ripple is the AC component superimposed on DC, calculated as Vr = I/(fC).
How to reduce ripple in rectifier output?
Use larger filter capacitors or regulators to smooth DC output.
