Discussion Overview

The discussion revolves around designing a machine that outputs current and voltage in phase, starting from an input where current and voltage are out of phase. The context includes a homework assignment related to electrical engineering concepts, particularly focusing on inductive motors and power factor correction.

Discussion Character

  • Homework-related
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant expresses confusion about how to design a machine to achieve in-phase current and voltage from an input that has them out of phase.
  • Another participant requests more information about the input source and the characteristics of the machine, suggesting that the problem may relate to power factor correction.
  • A participant clarifies that the assignment is about an inductive motor with main supply input and emphasizes the need for current and voltage to be in phase.
  • There is a suggestion that achieving in-phase output may involve equalizing inductive and capacitive reactance, hinting at resonance in an LRC circuit.
  • One participant encourages further reading on power factor correction, providing a link to a Wikipedia article.

Areas of Agreement / Disagreement

Participants express varying levels of understanding and clarity regarding the problem. While some suggest approaches like power factor correction and resonance, there is no consensus on a specific method or solution to the problem presented.

Contextual Notes

The discussion lacks specific details about the input voltage and current levels, the impedance of the source, and the exact requirements of the machine design, which may affect the proposed solutions.

hi,
i m struck in a problem. i have the machine whose input has current and voltage(both have different phase(it may be any)). i want to design a machine whose output has current and voltage both inphase. can anyone help me out. thanx

Welcome to the PF. I think we need more information in order to help you. You need to specify the source of the input voltage and current (including the impedance of the source and the voltage levels), and you need to specify the characteristics of the "machine". Is this power factor correction of AC Mains input into an inductive motor-based "machine" or factory? Is this a homework assignment, or an industrial question?
 
hi,
actually it is home assignment and instructor has left everything on our assumption i-e level of current/voltage or impedence of source.basically input to inductive motor is main supply the output (required) should ve current and voltage inphase.please help me out i m unable how to start the problem even.
i have also send u mail via hotmail. i don't know the actuall method to contact u i-e from here or via hotmail. thanx
 
Your question is still very confusing.
Are you asking how to do power factor correction?

You just need the inductive and capacitive reactance to be equal (i.e. resonance in an LRC circuit).

Also, since this is homework, you need to post the actual question and your work thus far.
