A-6 Flashcards
A device that changes AC to DC
Rectifier
AC Circuit, when a rectifier allows current to flow in only one direction, the current in the circuit is said to be?
Forward Biased
What device is used to smooth out the pulsations of a rectified DC Output?
Filters
Half of the AC input is converted to a unidirectional DC output, the rectification is called?
Half-wave Rectification
When both alternations of the AC input are converted to a unidirectional DC output, the rectification is called?
Full-wave Rectification
Advantages of a full wave rectification over a half-wave rectification?
More power capabilities
In a half-wave rectifier, the peak inverse voltage rating for the diode must be greater than the _____ of the AC input?
Peak Value
Simplest way to reduce the ripple of a rectified output is to use?
A capacitor filtor
The change in voltage level is called?
Voltage regulation
Why are electrolytic capacitors generally used as filters?
Maintain voltage longer and available in large capacitances.
What is the main disadvantage of using only a capacitor for filtering?
It can have a poor voltage regulation
What is a Pi Filter?
A combination of a LC Circuit. Removes ripples at a further extent
What is Ripple frequency?
Number of output pulses of DC
What type of rectifier uses a single diode connected in series with an AC Load?
Half-wave rectification
