Short introduction about AC to DC conversion formula usage

AC to DC converter calculator can change the value of alternative current to direct current.

It can also work the other way round. It means it can also work as DC to AC calculator.

What are AC and DC?

Wikipedia defines AC as:

 “The electric current which periodically reverses direction and changes its magnitude continuously with time.”

Whereas DC is completely the opposite.

“DC is an electric current that has the same direction and magnitude all the time.”

AC to DC conversion formula

DC is equivalent to the average AC value in 90 percent of cases.

DC = 0.636 × Vp

AC = Vp/√2


Vp represents the peak voltage.

How to convert AC into DC?


What is DC voltage if the peak value of AC is 150 volts?


Step 1: Write down the formula.

DC = 0.636 × Vp

Step 2: Put the value of peak voltage into the formula.

= 0.636 × 150

AC to DC converter wiki

An AC-to-DC converter is an electrical device that converts AC (alternating current) power to DC (direct current) power. This type of converter is essential in many electronic devices that require a steady DC voltage for operation. In this article, we'll discuss the basics of AC to DC-conversion and how this process is accomplished.

AC power is the standard form of electricity used in homes and businesses. It is delivered to these locations in the form of an alternating current, which means the direction of the electrical flow switches back and forth many times per second. In contrast, DC power flows in a constant direction, which makes it ideal for electronic devices that require a steady voltage to operate.

The process of converting AC power to DC power is accomplished by a device known as a rectifier. A rectifier takes the incoming AC voltage and converts it to a pulsing DC voltage. This pulsing DC voltage is then filtered and smoothed to create a steady DC voltage that can be used to power electronic devices.

There are two types of rectifiers: half-wave rectifiers and full-wave rectifiers. A half-wave rectifier only allows half of the incoming AC voltage to pass through to the output, resulting in a pulsing DC voltage that is less efficient and less stable than a full-wave rectifier. A full-wave rectifier allows the entire AC voltage to be used, resulting in a more stable and efficient DC voltage output.

In addition to rectifiers, AC to DC converters often include other components such as capacitors, transformers, and voltage regulators. Capacitors are used to smooth out the pulsing DC voltage, while transformers are used to step up or step down the incoming AC voltage. Voltage regulators are used to maintain a constant output voltage regardless of changes in the input voltage or load.

AC to DC converters are used in a wide variety of electronic devices, from small battery chargers to large power supplies for industrial equipment. They are essential for the reliable operation of these devices and have become an integral part of modern electronics. By understanding how AC-to-DC conversion works and the various components involved, you can better appreciate the complexity of the electronic devices we use every day.
