# RECTIFIER #
--- Device which converts alternating current to Direct current called rectifier & process is known as rectification.
---A junction diode offers low resistance to flow of electrical current in one direction when it is forward bise and high resistance in opposite directions when it is reverse biased. This property helps to use the junction diode as a rectifier.
#TYPES OF RECTIFIER #
1. Half wave rectifier
2. Full wave rectifier.
# Half wave rectifier::--
_ During positive half cycle of AC input,the diode is forward biased and conducts current.
- During negative half cycle of AC input the diode is reverse biased and conduct no current.
- The output consist of positive half cycle of input AC voltage. While the negative half cycle are suppressed.
-- In half wave rectifier the rectifier conduct current only during the positive half of the input AC supply.
-- Means output will get for half cycle so called as half wave rectifier.
,#HWR s TUF is __ 28.7
Ripple factor -- 1.21
Peak factor -- 2
Form factor -- 1.57
Maximum rectification efficiency -- 40.6
#FULL WAVE RECTIFIER #
--In full wave rectifier, current flows through the load in both half cycle of the input AC voltage.
-- Full wave rectifier has two type::-
(1) centre tapped full wave rectifier.
(2) Full wave bridge Rectifier.

2.bridge full wave rectifier.
ह्यामध्ये 4 diode असतात. Positive half cycle ला D1 व D3 forward biase व Negative half cycle ला D2 a D4 reverse biase होतात. अशाप्रकारे positive half cycle व negative half cycle ला करंट pass होतो.

Rectifier
- Diode Rectifier. Uncontrolled Rectifier.
-AC convert to DC (Palseting DC)
The process of Rectification.
Two types of Rectifier .
1) Half wave rectifier.
- Where the output meets the positive half cycle is called a half wave Rectifier.
- used in one Diode.
- When AC positive cycle occurs, the diode works in forward bias.
- When Ac negative cycle occurs. the Diode works in reverse bias.
*Disadvantage
- efficiency has low.
- ripple factor more ( same camponant of ac are also present in DC).
- Transformer utilisation factor has less.
- R.M.S voltage, Avg voltage are less.
*Advantage .
- circuit is easy to understand .
- less component are used.
- cost is less.
- bulkeyness is less.
2) full wave rectifier.
- Where both positive and negative cycles meet the output it is called a full wave rectifier.
: Two subtypes of Full wave rectifiers:
a) center tapped full wave rectifier.
b) Bridge full wave rectifier.
A. Centre tapped full wave Rectifier.
- used in two Diode.
- when positive half cycle occurs.the diode d1 acts forward bias , and diode d2 acts reverse bias.
- when negative half cycle occurs. the diode d2 forward bias and diode d1 reverse bias.
- Since the load resistance is tapped at the center of the secondary winding of the transformer, it is called a center tapped full wave rectifier.
*Advantages
- ripple factor less than half wave rectifier.
- R.M.S voltage and Avg voltage more.
- efficiency has more than half wave rectifier.
- Transformer utilisation factor is more than half wave rectifier.
*Disadvantages
- centre tapping is to much very difficult.
- circuit is complicated.
2. Bridge full wave Rectifier.

- when negative half cycle occurs. the diode d2 & d4 acts as forward bias and d1 & d3 acts reverse bias.
*Advantage
- efficiency has more than half wave rectifier.
- Transformer utilisation factor more than half wave rectifier.
- ripple factor less than half wave rectifier.
- R.M.S. voltage and avg voltage more than half wave rectifier.
*Disadvantage
