AC to DC Voltage Calculator

Ever wondered how to get DC voltage from AC power? You’re not alone. Many engineers, electricians, and students deal with this every day. Our AC to DC Voltage Calculator makes it easy. You don’t need complex math or tools just enter your AC voltage, and the calculator instantly gives you the DC value.

We built this tool so anyone can convert AC (Alternating Current) voltage to DC (Direct Current) voltage quickly and accurately. Let’s explore how it works, what the formula means, and how you can calculate it by hand too.

How Do You Calculate AC to DC Voltage?

The relationship between AC and DC voltage is simple. You can find DC voltage by multiplying AC voltage by a constant factor.

The formula is:

Vdc = Vac × 0.636

Where:

• Vdc = DC Voltage (volts)
• Vac = AC Voltage (volts)

This 0.636 factor comes from the average value of a sine wave over one half-cycle. It’s based on the ratio of the average to peak voltage in AC signals.

So, if your AC voltage is 60V, here’s the math:

Vdc = 60 × 0.636 = 38.16 volts

It’s that simple. No fancy physics needed just a quick multiply.

What Is the DC Equivalent of 230V AC?

Let’s take a real example. Suppose you’re using standard household power of 230V AC. To find its DC equivalent:

Vdc = 230 × 0.636 = 146.28 volts

That means a 230V AC source roughly equals 146.28V DC. This value helps when designing rectifiers or power circuits that switch between AC and DC systems.

How to Convert AC Current to DC Voltage

Converting AC to DC is more than just math it’s how modern electronics work. Your phone charger, for instance, converts AC power from your wall socket into DC power for your battery.

Here’s how the process happens in practice:

1. Rectification: The AC signal passes through diodes, which allow current to flow in only one direction.
2. Filtering: A capacitor smooths out the ripples, creating a steady DC voltage.
3. Regulation: Voltage regulators ensure the DC output stays constant even if AC fluctuates.

But if you only want to find the DC voltage value from a known AC voltage, the simple 0.636 factor is all you need.

How to Use the AC to DC Voltage Calculator

Using our calculator is as easy as flipping a switch:

1. Enter your AC voltage value (for example, 120).
2. Choose your input and output units (like volts or kilovolts).
3. Click the Calculate button.
4. Instantly, you’ll see the DC voltage result and the step-by-step math.

Our calculator shows each step clearly so you can learn while you calculate.

Example Calculation

Let’s say you have 11V AC and want to find the DC voltage.

Vdc = 11 × 0.636 = 6.996 volts

This means 11 volts of AC is equal to about 7 volts of DC. The tool will display this instantly, with every calculation step explained in plain English.

Whether you’re checking the DC output of a rectifier or just curious about how voltage changes, this tool gives you instant answers. No more guessing or manual math just type, click, and get the result.

FAQs

What is the formula to convert AC to DC?

The formula is simple: Vdc = Vac × 0.636

Why multiply by 0.636?

Because 0.636 represents the average value of a pure AC sine wave when converted to DC.

What’s the DC equivalent of 230V AC?

It’s about 146.28V DC.

Can I use this calculator for current (amps)?

No, this calculator is for voltage conversion only. Current conversion depends on load and resistance.

Is this calculator accurate?

Yes, it uses the standard conversion factor used in electrical engineering handbooks.
