AC to DC Voltage Calculator

Calculate DC Voltage from AC Voltage

Formula

To calculate the DC Voltage (Vdc) from AC Voltage (Vac):

\[ Vdc = Vac \times 0.636 \]

Where:

What is AC to DC Voltage?

AC to DC voltage conversion is a process that transforms alternating current (AC) voltage into direct current (DC) voltage. This is commonly done using a rectifier. The formula provided gives a quick estimate of the DC voltage derived from the peak AC voltage by multiplying the AC voltage by 0.636, which represents the average value of a sine wave over one half-cycle.

Example Calculation 1

Let's assume the following value:

Using the formula:

\[ Vdc = 120 \times 0.636 = 76.32 \text{ volts} \]

The DC Voltage is 76.32 volts.

Example Calculation 2

Let's assume the following value:

Using the formula:

\[ Vdc = 230 \times 0.636 = 146.28 \text{ volts} \]

The DC Voltage is 146.28 volts.
