This calculator makes electrical work simple, clear, and fast. Whether you’re a student, technician, or engineer, you’ll find it easy to use and understand.

What is Rectifier Voltage?

Rectifier voltage is the average output voltage that comes from a rectifier circuit after converting alternating current (AC) to direct current (DC).

In a full-wave rectifier, both halves of the AC waveform are used. The result is smoother and more efficient DC output compared to a half-wave rectifier.

The Rectifier Voltage (Vr) depends on the peak voltage (Vm) of the AC input and can be calculated using this simple formula:

Vr = 2 × Vm / π

Where:

• Vr = Rectifier voltage (in volts)
• Vm = Peak voltage (in volts)
• π = Pi (3.14159)

This means the rectifier voltage is about 0.637 times the peak voltage.

How to Calculate Rectifier Voltage

You can easily find the rectifier voltage by following these steps:

1. Measure or note the peak voltage (Vm) of your AC signal.
2. Multiply it by 2.
3. Divide the result by π (3.14159).
4. The final value is your rectifier voltage (Vr) in volts.

Example:

Let’s say the peak voltage (Vm) is 37 V.

Now, apply the formula:

Vr = 2 × 37 / 3.14159

Vr = 74 / 3.14159

Vr = 23.55 V

So, the rectifier voltage is 23.55 volts.

How to Use Our Rectifier Voltage Calculator

Using our online calculator is as easy as flipping a switch. Here’s how you do it:

1. Enter the peak voltage (Vm) in the input box.
2. Choose your input and output units (V, mV, kV, or MV).
3. Hit the Calculate button.
4. Instantly see your result with a full step-by-step explanation.

You’ll also see each stage of the calculation from unit conversion to the final voltage result.

Why Rectifier Voltage Matters

Rectifiers are everywhere inside your phone chargers, power supplies, and even solar inverters. The rectifier voltage shows how much DC voltage you’ll get from an AC input.

A higher peak voltage means a higher rectifier voltage. That’s why it’s important to understand the relationship between the two.

Our tool makes it easier to test and predict real-world circuit performance.

FAQs

What is the use of a rectifier?

A rectifier converts AC (alternating current) into DC (direct current). DC power is used in most electronic devices and circuits.

Can I use this formula for half-wave rectifiers?

No. The formula Vr = 2 × Vm / π is for full-wave rectifiers only. Half-wave rectifiers have a different formula: Vr = Vm / π.

How does the peak voltage affect the rectifier voltage?

The rectifier voltage is directly linked to the peak voltage. If the peak voltage increases, the rectifier voltage also increases.

What’s the average DC voltage from a full-wave rectifier?

It’s about 63.7% of the peak voltage, as shown by the formula Vr = 0.637 × Vm.

Can I convert the result to millivolts or kilovolts?

Yes. Our calculator lets you switch between volts, millivolts, kilovolts, or megavolts easily.
