What is rectifier and what is its use?
rectifier, it is a n electrical device that converts ths high votage carrying AC to low voltage carrying DC
Which rectifier is not directly operated from mains?
Because , the high voltage can destroy the diodes used in the rectifier .
Which electronic devices conduct during fly back?
high voltage rectifier
How can capacitor smooth or reduce the ripple of the voltage produced by the 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.
What is the difference between a transformer and a rectifierwhich are found in a PC power supply?
The rectifier is what changes your AC into DC that the computer can use. Transformer raises or lowers the voltage. So you have 110 volts AC coming into your computers power supply. The Rectifier circuit in there changes the AC voltage to DC voltage but it is still to high for the computer use. The transformer lowers that voltage down to the various voltages that your computer needs
What are the Importance of of peak inverse voltage in rectifier service?
What are the Importance of of peak inverse voltage in rectifier
What device is also called a rectifier?
A rectifier is an electronic device that changes an AC voltage to a DC voltage.
Can zener diode used as rectifier?
Yes **************************************** Yes they can but there are pitfalls. A normal diode will have a high reverse breakdown voltage. A zener has a relatively low breakdown voltage (its "zener"voltage). If a zener diode is used as a rectifier it must have a zener voltage at least twice the peak of the applied a.c.
Why an op-amp diode rectifier called as a precision rectifier?
In a rectifier made of just diodes, the diodes have a voltage drop, resulting in a lower DC output voltage. By introducing an Op-amp, this voltage drop can be overcome. Since there is no voltage drop caused by the diodes, the rectified signal is not changed by the rectifier, so it is called a precision rectifier.
What is rectifier welding machine?
A welding rectifier takes in the a/c output of a welding transformer, and the output is d/c. Used with old school welding transformers which were all a/c, in order to get d/c for use with low hydrogen rods etc.
Why bridge rectifier is prefer over center type rectifier for low voltage applications?
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.
What is the disadvantage of using the centre tapped full wave rectifier?
it can be driven by a single source voltage, such as the untapped secondary of a transformer or directly from the power line. The peak reverse voltage that can be tolerated is 2x the reverse breakdown of the diodes.
