HALF-WAVE RECTIFIER. A circuit that uses one cycle in an alternating
current to produce direct current. A Half-Wave rectifier circuit only generates DC from either the positive or negative cycle of the AC input, but not both. Note that the Half-wave Rectifier circuit does not require a center tap transformer.
Other Rectifier circuits; Full-wave Bridge Rectifier [center tap transformer].
Full-wave Bridge Rectifier [four diode].
Half-Wave Rectifier Circuit
The half-wave rectifier circuit is not used that often in electrical circuitry. As the graphic shows the output is far from a steady state DC output and would require a large amount of filtering. However by using a full-wave circuit [link above] the output is DC with only a small amount of ripple voltage [after a small amount of filtering]. No industrial grade power supply or commercial grade power supply would use a half-wave rectifier circuit.
In fact a half-wave rectifier circuit will only be found [if used] in a linear power supply, switching power supplies use a completely different approach.
Normally the diode used would be a 1N4004 or similar type.
