Full-Wave Bridge Rectifier Circuit Simulation

Overview

The Full-Wave Bridge Rectifier is an essential circuit used for AC to DC conversion. It utilizes four diodes arranged in a bridge configuration to rectify both halves of the AC waveform.

  • When the input Vin is positive, two diodes conduct, allowing current to flow through the load resistor R1.

  • When Vin is negative, the other two diodes conduct, ensuring the current through R1 always flows in the same direction.

  • The output voltage Vout is a full-wave rectified signal.

Mathematical Formulation

The output voltage in a half-wave rectifier is given by:

\[V_{out} = abss(V_m \sin(\omega t))\]

where:

  • \(V_m\) is the peak voltage of the AC source.

  • \(\omega\) is the angular frequency of the AC signal (\(\omega = 2\pi f\)).

  • \(t\) is the time variable.
