Great videos and audio equipment is always super subjective. But, this whole power regenerator and especially now the utility power clipping? C'mon, I work in electric utilities, with top of the line equipment, scopes, power quality analyzers, "syncrphasors" and the only time I have ever seen any AC waveform clipped is when a CT was driven to saturation. Harmonics, crappy power factor, "dirty" power sure, but never an AC sine wave clipped, especially at a residential location. Possibly at a heavy industrial location, maybe.... and I am reaching here. I don't know what equipment you are running to cause the power at your location, house, business where-ever to "clip", but if so that is a whole other issue that needs to be resolved and not band-aided. Second part, except in extreme cases a well built, quality electronic device should be able to handle and smooth out most power quality issues to begin with. Especially in a high end piece of audio gear, which would make this whole regenerator a moot point. Not trying to discredit anyone, like I said, audio equipment is highly subjective and opinionated, but from a power engineering aspect and these power conditioners for audio.... ehhhh EDIT: I'll go see if I can find any videos showing the clipping. I assume clipping is like audio clipping with clear defined, flat top and not a sinusoudal peak.

Gosh, yes, I just made a similar comment. This is just so super wrong. The term clipping is relevant on the output of an amplifier where the gain based output voltage exceeds the available max voltage. It's a totally different thing than running a higher load (current) on the mains wires. Any load causing a hard clipped AC mains voltage would be extremely noisy also and would be banned by FCC or CE. Any power regenerator with a clipped output would defeat the purpose of having it with the extreme noise involved.

I agree, and also I always think that the amplifier will convert AC to DC and MOSFETs will do the rest to create the audio waveform. If that power supply is properly designed all the noise will go away.. what do you think? I don't see any benefits using a power plant, unless you live in a mountain and the power grid is shit

@@pablovilchez7501 The noise shouldn't make it past the devices power supply if it's designed right. As far as mountains and noise on the line. You may have "cleaner" noise out in the mountains, vs in a city with more industry or electrical equipment around. There may be more power outages, but this isn't for that.

I used to downplay the importance of clean AC until I went to live in a rural residential area. My audio equipment was less noisy and sounded great in my city apartment but now it's noisy and prone to hum. I can hear my neighbors' posho mill through my speakers when it starts up. I guess we have overloaded our main electrical transformer. The house also has bad earthing, four houses connected by a single badly connected 20 gauge wire to earth. Voltage on earth circuit, hazard. After some research, I changed the ground-to-earth connection point, i.e. at the DACS' line output which made it a bit immune to switch-mode chargers in the household but it's still not perfect. For some reason, I can't float the DAC's ground. It leads to hum which subsides when the ground is earthed. I hope power regenerators also have a cleaned earth for equipment to ground to.

Within its rated power! Just like anything else, a hi fi system must be carefully planned. Good sound does not occur by luck, or just buying the same stuff as somebody else.

1:58 - _"... Within it's rated power..."_ - this is key. I always recommend x1.5 MINIMUM for power supplies or plants. x2 is best.

True. That plus the fact the larger passively cooled models aren't only noise-free (no fan) but to me make the most difference for one's system. So in order to preserve start grounding (no hum loops) and be able to plug in amplifier and not just source components, I wouldn't go below P15, and if a 20A outlet is available, a P20 may be even better.

This rule sounds like it would allow enough headroom for peak power demands. Yes, I'd prefer 2x, too. I would apply a similar rule to sizing amplifiers for speakers.

Traditional class A/AB power amplifiers have large capacitors for energy storage to handle transient music peaks, so the need for additional energy storage in the power regenerator is unclear. What about class D amplifiers with switch mode power supplies? Do they also store energy to handle peak demand?

@GBatya

D class amps have too small caps.

I once scoped the waveform at an outlet in a busy shopping center. What did I see? A perfect sine wave. Consesquently I am not a believer in the problems often cited for using a regenerator.

What was upline from the outlet to the utility's step-down transformer? Any large commercial complex should be wired so each renter has their own meter and then a direct connection to a distribution box, not unlike many houses on a street block. Also, any large facility will be connected to the utility's network through a local substation installed for a commercially zoned area.

@Evil_Peter

On top of that, the AC to DC conversion that's the first step in the regenerator is being done by the transformer in your gear and I've yet to see an amp transformer measured that didn't convert even a fairly noisy outlet AC output into perfect DC. Granted I've of course not seen such measurements for all gear but the ones I've seen haven't been really high end gear so one would expect such gear to have better transformers, not worse.

Stay safe!

This is wrong. The AC power does not go in a state of clipping due to overload. Clipping is a thing that happens in an amplifier when the intended output voltage exceeds the available voltage. On the AC mains, you don't see clipping. What you see is a drop in the sine wave voltage that can be purely resistive or have some wave distortion to it.

@janinapalmer8368

This is true but I assume the gain of the 60Hz amplifier / driver is regulated as to NOT go clipping as it drives the power transformer... I also assume the output to the audio equipment comes directly from the secondary winding of the power transformer..

@@ThinkingBetter Regrettably the newer versions don’t actually fully regenerate the power like the originals did. Instead they ride on top of the AC mains and more or less act as active voltage regulators so there is still a fair bit of distortion, but not as much as the raw AC. At any rate no regenerator should ever “clip” but go into overload protection instead and shut down. This is all purely academic, however, as equipment just chops it up onto harmonic rich half-wave DC after the secondaries or passes it through a PFC circuit which converts it into semi-regulated high voltage DC to power an SMPS.

Not UL or ETL, or ULc, or CSA independent lab tests, for safety etc. Unsafe at any voltage? Why not tests for such expensive stuff? UL ETL matters. In commercial installations, and places of assembly, EC's most likely need UL listed stuff in porder to pass AHJ inspections. Why doesn't PS have UL listed stuff, UL, it matters.
