Rectifier A rectifier is an electrical circuit or device that converts periodically reversing alternating current (AC) into unidirectional direct current (DC). Rectifiers have numerous applications, although they are most commonly encountered as components of DC power supplies and high-voltage direct current power transmission systems. Rectification can be used for purposes other than generating direct current for use as a power source. There are two types of rectifier circuits: 1) Half wave rectifier and 2) Full wave rectifier. Half Wave Rectifier When a AC waveform is applied and when half of the AC cycles gets rectified, it is called as half wave rectifier. The output voltage of the half wave rectifier is not pure DC as the AC components are present in this voltage. This AC component is called as ripple voltage. In half wave rectification, the rectifier only conducts during the positive half cycles of the alternating current (AC) supply. During negative half cycles, no current is c...
