Enter the maximum or peak voltage (volts) into the calculator to determine the Rectifier Voltage. 

Rectifier Voltage Formula

The following formula is used to calculate the Rectifier Voltage. 

Vr = 2*Vm / pi 


  • Where Vr is the Rectifier Voltage (volts)
  • Vm is the maximum or peak voltage (volts) 

To calculate the rectifier voltage, multiply the peak voltage by 2, then divide by pi.

How to Calculate Rectifier Voltage?

The following two example problems outline how to calculate the Rectifier Voltage.

Example Problem #1:

  1. First, determine the maximum or peak voltage (volts). In this example, the maximum or peak voltage (volts) is measured to be 37.
  2. Finally, calculate the Rectifier Voltage using the formula above: 

Vr = 2*Vm / pi 

Inserting the values from above and solving the equation with the imputed values gives: 

Vr = 2*37/ 3.14159  = 23.55 (volts)

Example Problem #2: 

Using the same process as example problem 1, we first define the variables outlined by the formula. In this case, the values are:

maximum or peak voltage (volts) = 40

Entering these values into the formula or calculator above gives us:: 

Vr = 2*40 / 3.14159  = 25.464 (volts)
