Phase Difference Between Two AC Signals: Can it be Zero?

Click For Summary

Discussion Overview

The discussion revolves around the possibility of achieving zero phase difference between two sinusoidal AC signals generated by separate generators, specifically in the context of combining their outputs to achieve a higher current without amplitude reduction due to phase differences.

Discussion Character

  • Debate/contested, Technical explanation, Experimental/applied

Main Points Raised

  • One participant inquires about the feasibility of making the phase difference between two 220V AC signals zero.
  • Another participant emphasizes the dangers associated with working with high voltage AC signals and questions what means are available to influence the phase.
  • A participant explains their situation involving two generators producing 220V and 1A each, expressing concern that the phase difference could reduce the effective amplitude when combined.
  • One suggestion is made that the generators should be mechanically coupled to ensure they rotate together, which could help in synchronizing their outputs.
  • Another participant warns that it may be more cost-effective to purchase a new generator rather than attempting to synchronize the existing ones.
  • The thread is ultimately closed due to concerns about safety when inexperienced individuals work with AC mains voltages.

Areas of Agreement / Disagreement

Participants express differing views on the methods to achieve zero phase difference, with some suggesting mechanical synchronization while others propose purchasing a new generator. The discussion remains unresolved regarding the best approach to take.

Contextual Notes

The discussion highlights the limitations of working with separate generators and the potential risks involved, particularly for those lacking experience with high voltage AC systems.

If i have two sinusoidal ac signals of 220V with the different phase angle i.e. there is some phase difference between them. Then can i make the phase difference zero?? Please tell

Hello akash, :welcome:

You should realize that 220 V can kill you !

What do you have available to influence the phase ? -- if anything at all
 
Ya i know it's dangerous, but i have to do it , Basically i have two generators who generates 220V ,1A current, and i have to add up to make it 2A, 220 volt, but the problem is that both currents are having some phase difference and this phase difference may create problem, means it can reduce the amplitude. So please tell some possible solution for this..

The generators need to be on the same shaft so they rotate together, fixed together so they rotate exactly together all the time.

Otherwise, expect it to be far cheaper to buy a new 2A generator.
 
Thread will remain closed because of the danger involved when an inexperienced person tries to work with AC Mains voltages.
