What are applications of rectifiers
running a.c motots
there is no need of bulky centre tap in a bridge rectifier. TUF(transformer utilisation factor) is considerably high. output is not grounded. diodes of a bridge rectifier are readily available in market. *the PIV(peak inverse voltage) for diodes in a bridge rectifier are only halfof that for a centre tapped full wave rectifier,which is of great advantage.
bridge rectifier is the best rectifier.
A bridge recifier is a full wave rectifier. It takes each part of the AC waveform, rectifies it and adds them together, giving a smoother output compared to a half wave recifier. They are used in simple power supplies, using a mains transformer, a bridge rectifier and a smoothing capacitor. Further regulation can then be added for stable power supplies.
It's the only way to accomplish full-wave rectification of AC without a center-tapped transformer winding.
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.
A silicon-controlled rectifier is a semiconductor device that is used as a switch in an electrical circuit. It's a solid state direct current (DC) electronic switch. There is a ton of information including a detailed description of the SCR and a list of applications at the Wikipedia article. A link is posted below.
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.
