Adhoc Voltaggio VS Pivot Raizin (Voltage Stabilizer) - Hardware Comparison.wmv

[nikushim666]

From a electrical engineering standpoint it wont have any real impact on a vehical. The function is allready built into every car as part of the alternators full-bridge rectifer circuit. If your having issue with power drops in the line signal than you are probley over drawing from the system and should upgrade your Alternator. Overall the product is a marketing scam aimed towards ricers.

[AndrewChan84]

@nikushim666 Well I don't know if you're a genuine commenter or hater so I'm just gonna objectively answer that.

The full bridge rectifier of the alternator only converts AC into DC and does not get rid of the electrical noise. When you full bridge rectify an AC, the sinusoidal wave which is rectified still have peaks and valleys. And at high revs the frequency of the noise increase.

We are not talking about large power drops here. We are talking electrical noise.

@AndrewChan84

The rect it self does not remove the noise, hense "Full bridge rectifer circuit", keywords there is circuit (not intigrated circuit) Inside a alternator the circuit consists of a rectifier a capacitor/inductor and overdraw failsafe (commonly zener diodes). The capacitor and inductor are what remedy the noise. Besides the point noise will have no impact on the ignition system anyways (considering it operates off a 30+khz disruptive discharge coil).

[AndrewChan84]

@nikushim666 a 4-banger at 3000rpm will have a discharge rate of 100Hz. That means the primary windings of the ignition coil will drain a spike of current once every one hundredth of a second, creating some noise in the line voltage.

So I don't see why this doesn't have an effect. Not to mention that sparks fire at 30,000 volts, and a 0.3 volt drop during that every one hundredth of a second, will lead to 800 volt drop at the secondary winding.

[AndrewChan84]

@nikushim666 a full bridge rectifier with its capacitor doesn't completely remove the noise. It is not just the alternator but the various loads in the car that drain current in a ripple fashion. This overlapping of noise from various source creates its own harmonics as well. So adding a low internal impedance (low ESR) caps in parallel to the line voltage isn't such a bad idea.

[nikushim666]

@AndrewChan84

EE wise a capacitor is almost always used in conjunction with a FBR IC package. Every alternator i have remanned contained one. The switch PS circuits on the ECU and ICU systems also contain noise reduction in them one from or another (primary to reduce noise created by ignition coil). Only time i can see them not having them is if it was remanned using substanrd aftermarket parts or just cheaply made with a inadaqute uF rating or low tolerence(precision) parts.

[AndrewChan84]

@nikushim666 Nevertheless they are marginal in their noise filtering ability. The whole point of this device is to create a larger capacitance, with minimal internal impedance, and high frequency response so it can adsorb even high frequency/short time interval spike type of electrical noise.

[AndrewChan84]

@nikushim666 And if the embeded capacitors in the alternator and ECU is enough to charge, why running the car without battery is detrimental? That shows that the battery is still being relied on to hold to voltage and get rid of some spikes right? Only thing, the battery itself has a high internal impedance so it doesn't absorb high frequency noise.

I wanted to stop selling this because of controversies, but due to popular demand I'm resuming.

[TonkatrainHONKHONK]

@AndrewChan84 Does the noise even matter in a car? I don't see how that would cause an impact on performance and any electronic device for use in a car should have the ability to deal with noise from the start.

[AndrewChan84]

@TonkatrainHONKHONK well, believe it or not, there is still something to be gained from reducing the remaining chunk of noise... :)

[MW2VideosCenter]

Hi, I have an Acura TL 06 and I want to gain some power is Pivot Raizin good for that? thx

[AndrewChan84]

@MW2VideosCenter Sorry for the late reply. From what I've gathered from my customers, these sort of product works better on cars less than 2000cc (naturally aspirated). Im selling the Voltaggio btw

[125varma]

hmmm... If I install and small 12 volts motorcycle battery under my hood and connect it to the car battery, I think it should do the same job, no? On the other hand, after starting, you can remove the battery completely and the car will go on working normally. basically battery is out of the circuit. So I'm wondering how this device is gonna help? Please help me understand :) Peace

[AndrewChan84]

@125varma Batteries and capacitors have different impedance profile. While battery is capable of churning a hundreds amps when put to a high load, is has very bad frequency response to incoming noise. The battery does not absorb high frequency voltage ripples, and the ripples end up getting absorb by the other components. Low ESR caps have exxellent frequency response.

This is not a power storage device, its a noise filtering device.

[SuperR31]

mega raizin ftw

[AndrewChan84]

@SuperR31 mega raizin cost 3 times and this has similar performance. :)

[LauxHawk]

Ok...I see what the intention is. The electricity goes into the device and the capacitors smooth out any ripple that's present. But how the hell does that work through the cigarette lighter? It can smooth out the entire car's electrical system must by going through the cigarette lighter? Hmm.

[AndrewChan84]

@LauxHawk Since it is not doing any high-current filtering, it can go through the cigarette lighter. It smooths out high-frequency ripples but not so much of high-current ripples.

[LauxHawk]

@AndrewChan84 I see. That makes sense. Those are Lelon/Xicon caps right? I'd like to see some Japanese caps since it's being used in a car. But whatever is most economical I guess.

[AndrewChan84]

@LauxHawk Those are not Lelon/Xicon caps. We have our manufacturer cuztomize it for us to our specs in terms of dimensions, ESR, ripple-current handling, capacitance and tolerance. We want our caps to be as robust as possible for an aluminium electrolytic, so we maxed out on many of these factors, especially ESR. Our ESR is measured to beat most solid caps, which is why we are able to get results on a bigger range of cars.

[AndrewChan84]

@LauxHawk Here is some essay on the product: w w w. adhoc- tech- sci. c o m / pd-vs-aa. h t m l

[LauxHawk]

@AndrewChan84 Yeah sorry don't want to sound obnoxious. Anyway, really love the design.

[AndrewChan84]

@LauxHawk nothing obnoxious

[abunaiN1]

so witch is better ?

[AndrewChan84]

@abunaiN1 Price wise and performance wise, the Voltaggio is better.
