very familiar si sir master circuit sa circuitry ng motor ah. very well said.

sir, sa ub, any particular component na gumagamit ng ac supply from stator? wala yata ano?

ang alam ko dati yung mga old motorcycles meron mga BULB lang aside from that wala na.

now adays pinadaan sa rectifier to rectify that AC then voltage regulator to regulate it on a specified level para iwasan ang putukan ng bumbilya at lahat ng accessories.



AN ARTICLE RELATED

The coil is connected to the bikes ground on one side. The other side of the coil has a (usually yellow) wire, which will be connected to one side of the headlight. The other side of the headlight hooks up to ground. The ground connection closes the loop back to the lighting coil.

Problem is now, that the coil will have an output voltage that is related to the rpm of the engine. The higher the engine is revved, the higher the voltage generated by the coil will be (technically this is not quite true, self inductance and DC resistance in the coil will limit the output at higher rpm, but that is beyond the scope of this story).

There is another problem to deal with. If you hook up a larger load to the coil (a higher wattage bulb) the output voltage of the coil will go down. If you hook up a load that is smaller than the output of the coil, the voltage will go over 15Vac at higher rpm, blowing the headlight bulb.


so i wonder if you have a defective R/R and you need a headlight at night.

then temporary connect a bulb on your stator

VOILA instant headlight, but of course it will only be effective if at a certain RPM.

ANS. It only converts AC voltages to DC voltages for specific application wherein DC voltages and current is needed.

whatever DIODE you have on your hand and connect it to an AC voltages with the right anode cathode configuration, you'll get + line and - line at the output. with same power as the input.


EVEN using INDUSTRIAL DIODES wont do such thing as raising up power requirement for intended applications.


RECTIFIER--------doesnt charge your battery...it only converts AC to DC whatever polarity you may incorporate the diode---..its the whole system.


STATOR--->>RECTIFIER-(converts AC to DC)--->>REGULATOR--(clamp DC converted to a level)--->>SENSOR--(compose of FET)--(inside the R/R that act as a switch)------->>> then your battery

[STOCK HOLDER]

Sir kung stock lang po ang scooter ano pong mas-effective yung voltage stabilizer or yung fast charging rectifier ?

Kasi sir gusto ko pong mag-upgrade ng busina,ang gusto ko pong ikabit ay yung stebel compact nautilus horn.

Salamat po.

[Master Circuits]

SO theres no terms such as THIS in an electronic dictionary or related terms.

UNCONTROLLED RECTIFIER
PHASE CONTROLLED RECTIFIER
SWITCH MODE RECTIFIER

some common terms ng rectifier.......

FAST CHARGING RECTIFIER VOILA


@stck holder

stebel horn dont need replacement of your R/R

use a relay to compensate the sudden load the horn will give to the battery. yun ang nakakadiskarga na baterya. yung unang palo ng current

ever wonder bakit ang electric starter ng mga motor may relay...yun ang gamit nun.

yung contact ng relay ang sumasalo ng sudden spike ng current.

wala ka na dapat baguhin pa.

[SyMan]

sir are we talking about voltage here? normal ang fast-charging celfon chargers have the same voltage output. the difference is their current output. normal chargers have 500ma and below while fast chargers have 800ma and above.

The 500ma and 800ma are the rated current outputs of the chargers and not the actual charging currents. To charge faster, you need a higher current than usual so it is obvious that you need higher current rating. However, remembering Ohm's law (V=IR), at constant resistance, you need to increase the voltage to have an increase in current. Also, chargers limit their output current to protect itself. At initial charging, the current will be close to the rated current limits and will taper down as the battery approaches full load.

@StockHolder

Master Circuit is right that you need a good relay but may I add that you use a new bigger wire at least #10 or bigger. Connect it directly to the battery with fuse then to the relay then to the horn. Big wires have less resistance per foot and therefore a must for high current loads, while relays separate the power lines from the control lines which are usually smaller wires. This is a frequent mistake by most installers of high power accessories, they always overlook the use of heavier wires by just using a relay and the old wirings which were designed for lower loads.

Lets just assume that the small wire has total resistance of 1 ohm. If your load is only 1 amp, then the power dissipated by the wire is 1watt. If your load is now 5 amps, the power dissipated is now 25w(P=IxIxR). As you can see, the wires alone can consume more power than your accessories(but this is just an exaggeration) The internal resistance of wires per unit length is inversely proportional to the its cross sectional area. Specially important for electrical motors(air horns), the starting current is very high, sometimes up to 3x the normal operating current, the heavier the wires used, the better. This is what causes the lights to flicker or dim when you use your horn, therefore using heavy wires will minimize this flickering. All of this assumes that you have a charging system in good condition.

it had been explained many times sir. mga bro, yun paulit-ulit magtanong dyan, umpisahan nyo magbasa sa page 1 ng thread. nagagalit na si master circuits.

is this really true sir? pano sasaluhin ng contact ng relay ang current spike? the contact of a relay is just the same as the manual switch considering they have the same current rating. if your relay contact is rated 10A, and your manual switch also has 10A rating, either of the two will have no advantage over the other.

[hacker]

At initial charging, the current will be close to the rated current limits and will taper down as the battery approaches full load.

there are smart chargers that can sense how much the battery being charged is already loaded.

[Master Circuits]

master! sabi mo kasi " the rectifier regulator only converts ac then regulated to a particular level for desired application such as charging the battery" and "RECTIFIER--------doesnt charge your battery...it only converts AC to DC . pls enligthen everybody pati narin ako. bale ano ba talaga ang silbi nag rectifier? at ano naman ang cause bakit kaya nade drain ang battery? bale kung nadrain ang battery walang connection ito sa rectifier dahil according sayo the rectifier only converts ac to dc. tama ba?

as what i have known about rectifier YES, it only converts ac to DC then feed to a voltage regulator then to the battery.

you cant charge a battery using AC voltages.

thus kailangan mo ng rectifier to convert it and feed it to the battery of course at a safe level.


bakit na de drain ang battery?

too much load on the battery makes it suffer and drain that your charger cant fill up the drain time since DISCHARGING battery is faster than the charge time.


i have inputed an article regarding electrical on other thread for all of those asking about stator and R/R, it will help everyone here.

Sir, you are enlightened..

but as the title of this thread progresses

"FAST CHARGING RECTIFIER"

are you enlightened about the title itself,


maybe if the thread title was

"FAST CHARGING REGULATOR"

pare parehas lang ang gamit ng voltage regulator,

pero iba iba ang way nyang mag bigay ng charge current off state at on state.

yung mga standard, they are designed to work at its optimum level, computed for a factory setup bike.


yung mga aftermarket, they were designed for maximum efficiency such as said at the top. giving the highest possible charge current and charging voltage. at the desired RPM


a voltage regulator depends on the RPM of engine when to give a charge current to the battery, after it sense it is in ned of charge

iba iba din ang charge current ng bawat voltage regulator, di pare parehas yan.


if yun ngang sa yo ay umubra den its good to hear that, you just found the perfectly R/R for your machine and the habit how you ride your bike.

[Master Circuits]

is this really true sir? pano sasaluhin ng contact ng relay ang current spike? the contact of a relay is just the same as the manual switch considering they have the same current rating. if your relay contact is rated 10A, and your manual switch also has 10A rating, either of the two will have no advantage over the other.

Try it sir you'll know the difference

just think of your electric starter for reference, they wont put relay there without any purpose, or try experimenting by removing the relay and direct it to the elctric starter to see what will happen to your switch he he


Definition of: relay

An electrical switch that allows a low power to control a higher one. A small current energizes the relay, which closes a gate, allowing a large current to flow through.

i agree that the purpose of relay is to isolate the control line(low power) from load line(higher power) that's why i doubt that relay can filter spikes. it is the purpose of the manufacturers to put relays - for isolation. afaik, relay are not for filtering spikes, regulators do this.

if you would try not to use relay with the starter and use only a manual switch, what would happen to the manual switch is just the same as what would happen to the contact of relay. eventually both will get burned.

[deyncio]

NOTE:
explanations are in general and not limited to vehicles' rectifier/regulator.

yes, sir! it's a compliment!!!

my conclusion:
to have a fast charger, it should have a higher voltage AND amp rating.

but sir, i get a little confused on the underlined expalnations.
as i understand, FLUCTUATION is a variation in an extensive or intensive quantity, such as energy, density or voltage, from its spatial or temporal average.

i therefore think of the neg AND pos voltage fluctuations, but the 2 seem to have the same regulation capabitlity aside from the certain voltage SET on the variable regulator.

"there are two types of regulator. fixed and variable.

un fixed, kung ano yun indicated na output voltage nya, yun na yun. kahit may fluctuation ka sa input, the output would be the same. that's how it regulates.

yun variable naman same lang ng fixed. the only diffirence is you can vary the output. walang lalabas na voltage higher than your setting kahit may fluctuation pa sa input."

how high can we set a variable regulator's voltage to charge a certain battery faster? i assume percentage ito ng naturing na baterya, di po ba?

and given that we have a "variable fast charging regulator", when can we say that a battery is not or is overcharging if this will give us a stable higher voltage and regardless of fluctuations?

salamat po!
