BRIDGE W04M PDF

Evolution of rectifiers Rectifiers are mainly classified into three types: Half-wave rectifier , Center tapped full-wave rectifier and Bridge rectifier. In half wave rectifier, only 1 half cycle is allowed and the remaining half cycle is blocked. As a result, nearly half of the applied power is wasted in half wave rectifier. In addition to this, the output current or voltage produced by half wave rectifier is not a pure DC but a pulsating DC which is not much useful. In order to overcome this problem, scientists developed a new type of rectifier known as center tapped full wave rectifier. The main advantage of center tapped full wave rectifier is that it allows electric current during both positive and negative half cycles of the input AC signal.

It may be considered as DC voltage upon which is superimposed a very large ripple voltage. This kind of electric power is not very usable, because ripple is dissipated as waste heat in DC circuit components and may cause noise or distortion during circuit operation.

A filter may be as simple as a single sufficiently large capacitor or choke , but most power-supply filters have multiple alternating series and shunt components. When the ripple voltage rises, reactive power is stored in the filter components, reducing the voltage; when the ripple voltage falls, reactive power is discharged from the filter components, raising the voltage. The final stage of rectification may consist of a zener diode -based voltage regulator, which almost completely eliminates any residual ripple.

Snubber circuits[ edit ] Power-supply transformers have leakage inductance and parasitic capacitance. When the diodes in a bridge rectifier switch off, these "non-ideal" elements form a resonant circuit, which can oscillate at high frequency. This high-frequency oscillation can then couple into the rest of the circuitry.

Snubber circuits are used in an attempt to mitigate this problem. A snubber circuit consists of either a very small capacitor or series capacitor and resistor across a diode. For example, for a three-phase AC input, a half-wave rectifier consists of three diodes, but a full-wave bridge rectifier consists of six diodes. Half-wave rectifier may be considered as wye connection star connection , because it returns the current through the centre neutral wire.

Full-wave is more like delta connection, although it can be connected to the three-phase source of either wye or delta and it does not use the centre neutral wire.
