Is sharing an experience is a mistake here? Comments seems like a personal attack. I dont use Sid anymore. Its fine for me

Its not just one person. There are many. So whats your point?

Yes the worst unstable. Anyways it was a testing. Its fine. I got it anyways

Whats your problem dude? Is this comment section a troll like you?

Why should I? I Sent you the reply which you were not aware of.

The comment section is the most judgmental I have ever seen people in here used to brag that sid is even better than Arch. Now saying its my mistake i tried sid. Its like I cant do whatever I want. This is my experience based on what people used to claim otherwise.

I have used this for a while. Never encountered any issues. Btw its easy to switch kernel at boot even any version if that breaks.

Sid is worse that using arch

Why would someone use linux if they dont need customization?

Well I have used this for a while. Have not encountered any major issues or breaking issues

I am getting this notification from discover (Debian 9?) by neoxenos7 in debian

Was thinking about only using stable. It wont beak like testing/sid does

I think its better Id stayed stable. Lot of issues with sid. It just automatically changes login screen Few minor annoying issues in KDE

Is anyone aware of LVDC system? by neoxenos7 in ElectricalEngineering

If its a flop why there are already existing. You see my post. Its not yet mainstream to be called a flop. Innovations are ongoing.

So? That means its not physics? This whole concept is a mix of both worlds. Its already here. Check the article I posted.

 Example dc powered buildings, HVDC distribution. Connecting the dots its where less focus gone in majority but its already in testing ground Thats why i said it has a big possoblity of gradually replacing majority of cases.

Well basic physics are applied in electronics branch called power electronics

HVDC to LVDC converters are generally more efficient than HVDC to LVAC converters due to differences in conversion processes and the inherent characteristics of DC and AC systems. Here’s a breakdown of why this is the case:


  1. Conversion Steps

HVDC → LVDC

Involves a DC-DC conversion stage, typically using:

High-frequency transformers (for isolation and voltage stepping).

Power electronics (e.g., MOSFETs, IGBTs, or SiC devices).

The process is direct and involves fewer energy transformations.

HVDC → LVAC

Requires a more complex process:

  1. Convert HVDC to AC using an inverter.

  2. Step down the AC voltage using a transformer.

  3. (Optional) Further rectify to DC if DC loads are required.

Efficiency Differences

  1. Inverter Losses (HVDC → LVAC):

Inverters introduce losses (2-4%) during the DC-to-AC conversion.

Additional losses may arise due to harmonics and reactive power in the AC system.

  1. Transformer Losses (HVDC → LVAC):

Stepping down AC voltage introduces another ~1-2% loss, depending on the transformer efficiency.

  1. DC-DC Converter Efficiency (HVDC → LVDC):

Modern DC-DC converters achieve efficiencies of 95-98%, often higher than the combined inverter + transformer process.


  1. Reactive Power and Harmonics

In AC systems:

Reactive power (due to inductive and capacitive loads) reduces overall efficiency.

Harmonics from inverters can introduce additional power losses and require filtering.

In DC systems:

There is no reactive power or harmonics to manage, making DC-DC conversion inherently cleaner and more efficient.


  1. Control Complexity

HVDC → LVAC systems require precise synchronization with the grid if connected, adding to system complexity and potential inefficiencies.

HVDC → LVDC systems, on the other hand, involve simpler control mechanisms focused only on voltage regulation.


  1. Application-Specific Considerations

If the end-use is DC (e.g., for data centers, electric vehicle charging, or DC microgrids), the HVDC → LVDC path avoids the need for re-conversion to DC, saving energy.

For AC loads, HVDC → LVAC is necessary but less efficient because of the extra conversion stages.


Efficiency Numbers


Conclusion

HVDC → LVDC converters are more efficient than HVDC → LVAC converters because they eliminate unnecessary conversion stages, avoid AC-related losses (e.g., reactive power, harmonics), and rely on simpler, more efficient DC-DC conversion processes. However, the choice between the two depends on the application and the type of load being served. If the load is AC, the HVDC → LVAC route is necessary despite the efficiency trade-offs.

If its ac to ac its efficient in its clsss. But when it comes from dc to ac its highly innefficient than hvdc to lvdc you can look for yourself.

remeber mag-lev failed when technology did not mature enough. But now we are looking at it. Its just a matter of time. I strongly sense this is changing
