The simple principle of a rectifier is to convert Alternating Current (AC) to Direct Current (DC)
it does this by only allowing the top half of the AC wave to pass through. The simplist rectifier is a Diode. If you place a Diode in line with an AC current you will get DC current. If you just use 1 diode it will be a really choppy DC current. The best bet is 4 diodes in a Bridge Rectifier configuration. This will give full wave rectification.
even after you've rectified the wave, it's still wavvy, So then you have to filter it to get it nice and smooth like the DC current you might get out of a Battery.

bridge rectifier is the best rectifier.
Where a single diode is used as a rectifier you get halfwave rectification when the sinus wave is going positive the diode will conduct but in the negative half of the cycle it will block the current flow so the result wave form will be only the positive half that will be available for half the period of the cycle the other half will be 0 Volt

Working the rectifier
such a control rectifier that control or rectifier single phase. for that purpose we used SCR that is called single phase controlled rectifier.
Bridge Rectifier DiodesIn a "bridge" rectifier there is 4 diodes In a "full wave" there are 2 diodes.In a "half wave" rectifier there is 1 diode.
Nothing will happen to the diode but that rectifier effectively becomes a half-wave rectifier.
when rectifier is on, the capacitor is almost transparent (it charges to the voltage provided from the rectifier) when rectifier is off, capacitor holds the peak voltage since it stored a charge during rectifier on time.
The population of International Rectifier is 2,009.
International Rectifier was created in 1947.
