Half-Wave Rectifier Example

This example demonstrates a half-wave rectifier. The diode allows current to flow in only one direction, effectively cutting off the negative portion of the AC input sine wave. The two voltage probes allow for a comparison of the input and output waveforms.

The simulation graph shows the input sine wave and the rectified output. The output voltage follows the positive half of the input sine wave and is approximately 0V during the negative half, demonstrating the rectifying action of the diode.
