AC to DC Rectifier Voltage Calculator

An AC to DC rectifier converts alternating current (AC) to direct current (DC). The output voltage of such a rectifier depends on the peak value of the AC input voltage. For a full-wave rectifier, the approximate DC output voltage is around 90% of the peak AC voltage.

Here’s a table that shows the approximate DC output voltage for different types of rectifiers based on the peak AC input voltage:

Rectifier Type	Approximate DC Output Voltage
Half-Wave Rectifier	Vpeak × 0.45
Full-Wave Rectifier	Vpeak × 0.9
Bridge Rectifier	Vpeak × 0.9
Three-Phase Rectifier	Vpeak × 1.35

Please note that these values are approximate and may vary based on the specific characteristics of the rectifier circuit and load conditions.
