Transformator's purpose on beneficent electric series to revamp indigenous tension PLN which is 220 Vrms becomes safe tension is utilized on lat electronic device. Since tension PLN is tension shuffle through therefore output tension from transformator also constitute succeeding AC tension will be revamped as tension DC by diodes on electronic series.
1. Half Wave Rectifier
Half Walf Rectifier is quits series of diode with resistive charges. Charges tension is undulate sinusoidal half wave already direktifikasi (disearahkan). Where is peaknya's point aproksimasi's ala equals peak of input tension (if utilizes transformator therefore tension be noticed for secondary tension). Charges tension average value is called also point dc is as big as 31,8 % of charges top tensions.
Vdc = 0,318 Vp
Happening ripple frequency on HWR or this Rectifier's Bridge is equal to line frequency.
fout = fin
On HWR usufructs from charges tension that constitutes output, having form a half wave if its entry tension as undulate as sinusoidal. On resulting current HWR as direct current. Output from HWR it is not desirable DC tension for electronics equipment because required just for electronics equipment is constant tension, resulting same tension by dry cell.
If utilize approaching both of, handicapped potential which is 0,7 v decreased deep inputs its formula become
Vp (out) = Vp (in) – 0,7 V
2. Full Wave Rectifier
Full Wave Rectifier contains transformer centertapped with 2 diodes and one charges interferences. Charges tension as sinewave as half wave already disearahkan by assesses peaknya aproksimasi's ala equals a half top of secondary tension.
Vdc = 0.636 Vp
Happening ripple frequency on FWR is as big as 2 source frequency times.
fout = 2 fin
Full Wave Rectifier all the same with two half wave rectifier. Effect from center tap, each rectifier have masuksama's tension with an a half secondary tension.
On full wave rectifier count utilizes second approaching therefore as
Vp (out) = Vp (in) – 0,7 V
Gbr b. Full Wave Rectifier
3. Rectifier's bridge
Rectifier's bridge contains 4 diodes. Its charges tension as sinewave as full wave already being led by peaknya's point aproksimasi's ala equals to assess its secondary tension. dc's point or on a par tension on charges is as big as 63,6 % peak's tensions chargeses.
rectifier's bridge have equality on full wave rectifier because bridge rectifier results output tension that equals full wave.
Gain utilizes type from full wave what does pass through center tapped is exhaustive secondary tension gets to be utilized.
Second approaching for bridge rectifier is
Vp (out) = Vp (in) – 1,4 V
4. Voltage Multiplier
Voltage Multiplier is 2 or more rectifier which result one dc's tensions that equals peak's tension multiple input (2Vp, 3Vp, 4Vp, dst). Power supply this was utilized on equipment gets high-tension or get low current as catode ray tube (picture tube on TV's plane, oscilloscope and computer display).
