How many diodes will a high output alternator usually contain?
Wiki User
∙ 10y ago
An alternator usually has 6 diodes in a full-wave rectifier for the main current output connected directly to the battery, and also another 3 for the secondary output to the voltage regulator, which feeds DC through slip-rings to the field coil in the rotor.

Does semiconductor lasers and laser diodes are similar?
Semiconductor lasers are made with laser diodes, with added circuitry to measure and regulate the diode current/output.
What is a super luminescent diode?
With their emission properties Superluminescent Light-Emitting Diodes (SLEDs) are closing the gap between Laser Diodes (LDs) and Light Emitting Diodes (LEDs).They offer the broadband optical spectra of LEDs and the spatial coherence of LDs. Compared to Laser Diodes and LEDs, SLEDs can be understood as • Spatial coherent broadband laser diodes with a beam-like output • Temporal incoherent laser diodes with a broadband spectrum • Speckle-free laser diodes with a short coherence length • Spatial coherent LEDs with a beam-like output
What is the square law detector?
It simply means that the DC component of diode output is proportional to the square of the AC input voltage. So if you reduce RF input voltage by half, you'll get one quarter as much DC output. Or if you apply ten times as much RF input, you get 100 times as much DC output as you did before. An increase of 3dB results in twice as much output voltage.All diodes will follow the square-law rule for small signals. We should choose one that is fast, so 1N4000- series power diodes are out. Any diode with a lot of capacitance is out. Diodes with a sharp I vs. V curve will give more output, so silicon diodes are less desirable. Schottky diodes are great, but they require DC biasing to get into the really curved part of the I vs.V curve. With zero bias, a germanium diode has very decent qualities (apart from nasty temperature effects). When Hewlett Packard makes square-law diodes using exotic semiconductors like gallium arsenide with molecular-beam-epitaxy machines, the result looks remarkably similar to a simple pointcontact germanium diode like a 1N34A.
Why an op-amp diode rectifier called as a precision rectifier?
In a rectifier made of just diodes, the diodes have a voltage drop, resulting in a lower DC output voltage. By introducing an Op-amp, this voltage drop can be overcome. Since there is no voltage drop caused by the diodes, the rectified signal is not changed by the rectifier, so it is called a precision rectifier.
Whats output on alternator for 1998 Toyota?
Not sure, but it falls between 85 and 100 amps.
What is the purpose of a diode in an alternator?
The diodes are part of the rectifier assembly that converts the alternator's AC output to DC. The alternator's charging output flows through six diodes in the rectifier assembly before it goes to the battery and electrical system.
What causes a auto alternator to go bad or short out?
the alternator belt could be slipping so check the belt, the wiring at the alternator could be faulty do a check with a multimeter. open the alternator and check the diodes .apply battery power and see if the rotor still spins inside the stator see current output
If one of the diodes in the rectifier is opens what should be possible output voltage?
low output
How does an alternator know how much voltage output?
Output of the alternator is controlled by the voltage regulator.
What are the wires for on alternator?
There should be a heavy wire called the Alternator output wire, It carries power from the alternator to power your accessories and to maintain your battery. The smaller wires usually in a plug are either the alternator's voltage sense, Stator/ACurrent/Tachometer output, regulator/indicator light. or if its an Externaly regulated alternator they will be alternator Field, Stator/ACurrent/Tachometer. hope this helps

Will alternator still work if the gauge is not?
An alternator does not need a gauge to work. It is used to monitor the output of the alternator.

What is alternator output in amps?
The alternator (or generator) of a vehicle is the unit that converts the mechanical energy from the drive-belt into electricity. Amperage (amps) are the output level of the alternator. Alternator part number, as well as output amps are specific to each vehicle.Another AnswerYour question is a little like asking, "How long is a length of string?"! The rated output current of an alternator depends on its rated output power rating and its rated terminal voltage. The rated output power can vary tremendously, according to the physical size of the machine.
What instrument measures alternator output?
An ammeter. It measures the electrical current output.
What are the advantages of Trapatt diodes over Impatt diodes?
Advantages of Trapatt:• higher efficiency than impatt• very low power dissipationAdvantages of Impatt:• This microwave diode has high power capability compare to other diodes.• Output is reliable compare to other diodes.
Fuse alternator 1995 mercury mystique?
I have a 2.0 1995 Mercury mystique the battery charge light was on no output on old alternator. Replaced alternator No output from new alternator "charge light out" (wiggle test wires& re-check wires) at alternator *still no output* is there a fuse that could be the problem or just another bad alternator... I would check the alternator plug before getting another alternator, it may be bad. And is a lot cheaper to replace.
