Bridge Rectifier Output Voltage Calculator

Formula

The formula to calculate the Output DC Voltage (Vdc) is:

\[ V_{dc} = V_{rms} \cdot \sqrt{2} - 2 \cdot V_d \]

Where:

\( V_{dc} \) is the Output DC Voltage (Volts)
\( V_{rms} \) is the Input AC Voltage (Volts)
\( V_d \) is the Forward Voltage Drop (Volts)

Bridge Rectifier Definition

A bridge rectifier is an electrical circuit consisting of four diodes arranged in a bridge configuration that converts alternating current (AC) to direct current (DC). It is widely used in power supply units where a stable DC voltage is required.

Example Calculation

Let's consider an example:

Input AC Voltage (Vrms): 10 V
Forward Voltage Drop (Vd): 0.7 V

Using the formula to calculate the Output DC Voltage:

\[ V_{dc} = 10 \cdot \sqrt{2} - 2 \cdot 0.7 \approx 11.9 \, \text{V} \]

This demonstrates that with an input AC voltage of 10 V and a forward voltage drop of 0.7 V, the output DC voltage would be approximately 11.9 V.
