Rectifier vs. Voltage Stabilizer (VS)

[BONG2Y]

---

to be honest with you...i really don't know the difference of these two.

I'm planning to put up more lights for my mio bike and i don't know what to buy...VS or rectifier
Anyone who can help me sight the difference of these two? I need your input before i'll purchase one for my bike.

Anyone can direct me on where I can buy cheaper but quality VS or Rectifer? Thanks in advance.

Rectifier

http://en.wikipedia.org/wiki/Rectifier

A rectifier is an electrical device that converts alternating current (AC) to direct current (DC), a process known as rectification. Rectifiers have many uses including as components of power supplies and as detectors of radio signals. Rectifiers may be made of solid state diodes, vacuum tube diodes, mercury arc valves, and other components.

A device which performs the opposite function (converting DC to AC) is known as an inverter.

When only one diode is used to rectify AC (by blocking the negative or positive portion of the waveform), the difference between the term diode and the term rectifier is merely one of usage, i.e., the term rectifier describes a diode that is being used to convert AC to DC. Almost all rectifiers comprise a number of diodes in a specific arrangement for more efficiently converting AC to DC than is possible with only one diode. Before the development of silicon semiconductor rectifiers, vacuum tube diodes and copper(I) oxide or selenium rectifier stacks were used.

Early radio receivers, called crystal radios, used a "cat's whisker" of fine wire pressing on a crystal of galena (lead sulfide) to serve as a point-contact rectifier or "crystal detector". Rectification may occasionally serve in roles other than to generate D.C. current per se. For example, in gas heating systems flame rectification is used to detect presence of flame. Two metal electrodes in the outer layer of the flame provide a current path, and rectification of an applied alternating voltage will happen in the plasma, but only while the flame is present to generate it.

Voltage stabilizer - Wikipedia, the free encyclopedia

A voltage stabilizer is an electronic device able to deliver relatively constant output voltage while input voltage and load current changes over time.

The voltage stabilizer is the shunt regulator such as a Zener diode or avalanche diode. Each of these devices begins conducting at a specified voltage and will conduct as much current as required to hold its terminal voltage to that specified voltage. Hence the shunt regulator can be viewed as the limited power parallel stabilizer. The shunt regulator output is used as a voltage reference.

The Zener diode and avalanche diode have opposite threshold voltage dependence on temperature. By connecting these two devices sequentially, it is possible to construct a voltage reference with improved thermal stability. Sometimes (mostly for the voltages around 5.6 V) both effects are combined in the same diode.

ang pangutana man pod naku bro kung ngano ang mga HID gamiton kay rectifier man instead of VS?

ang VS dili diay kaya ang power sa HID?...di man ko ganahan magtan-aw na mohinay ang siga sa ako mga suga kung dili ko mo-kumot sa gasolinador. it's better kung mag-steady lang ang siga sa akong mga suga na gamiton sa ako bike especially sa ako headlight.

What you'll need is a bunch of capacitors to compensate the sudden load from your lights when you switch them on. The battery cannot give quick response when you switch "on" these large load like headlights. Capacitors across your battery will give that quick response and they will charge faster also than batteries. With capacitors, mas dugay pud madaot imong battery or less ang iyang bun-og. Kung kuwangan gihapon sa imong required demand, mao na ang panahon patas-an nimo ang capacity sa capacitors or ang idle rpm at the cost of spending more fuel.

@ vernie so u recommend buying a VS instead of rectifier? is that right?

Voltage stabilizers or boosters in times of sudden current draw can really help but not to the point you won't notice some flicker on lights. There will still be some flicker on the lights but minimal than without the capacitors or voltage stabilizer. A Rectifier is only needed when you have an AC supply and only use DC out of it.

A Rectifier and A Voltage stabilizer are two different things that you cannot compare which one gives more boost.

i see...thanks for the input bro
