SINGLE-PHASE DIODE RECTIFIERS:-

Rectification is the process of conversion of alternating input voltage to direct output voltage. A rectifier converts AC power to DC power. In diode-based rectifiers, the output voltage can’t be controlled.

In this section, uncontrolled single-phase rectifiers are studied. The diode is assumed ideal as before.

A rectifier may be half-wave type or full-wave type. A half-wave rectifier is one in which current in any one line, connected to AC source, is unidirectional. However a full-wave rectifier has bidirectional current in any one line connected to AC surface.

A rectifier may be one-pulse, two-pulse, three-pulse, or n-pulse type. The number of pulses in any rectifier-configuration is obtained as under:

Pulse number = number of load current (or voltage) pulses during

one cycle of AC source voltage.

Single-phase half-wave rectifier is not used for industrial application because of poor performance. It is known as single-phase one-pulserectifier.
