Discussion Overview

The discussion revolves around designing an automatic charger circuit for a 12V 10A battery. The goal is to create a system that charges the battery to a specified voltage A and then stops until it drops to a voltage B, specifically using thyristors in the design.

Discussion Character

  • Homework-related
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant seeks to build a circuit that charges a 12V 10A battery to voltage A and stops until it reaches voltage B, specifically using thyristors.
  • Another participant suggests using a voltage comparator to achieve the desired charging control, referencing an op-amp implementation.
  • A participant challenges the comparator suggestion, stating the need for specific voltages A and B rather than A and -A, emphasizing the requirement to use thyristors.
  • Another participant proposes using a voltage divider to set the desired voltages A and B, suggesting that op-amps could be used as comparators to control the charger.
  • A later reply expresses a limitation in using op-amps and requests alternative ideas, indicating a preference for solutions involving only thyristors, diodes, and resistors.

Areas of Agreement / Disagreement

Participants have differing views on the components and methods to achieve the charging control, with no consensus on a specific solution. The discussion includes various proposed approaches but remains unresolved regarding the best method to implement the circuit.

Contextual Notes

Participants have not fully defined the parameters for voltages A and B, and there are unresolved assumptions regarding the circuit design constraints, particularly the restriction on using op-amps.

Homework Statement



i need to build a circuit which can charge a 12V 10 A battery to reach a votltage A and then stops charging until it reaches a voltage B it will rechrge again . i want to do this using thyristor

Homework Equations





The Attempt at a Solution


i found a circuit for a 12 v 4A it will reach A but i donno how to control B

no sir it won't work cz 1st i ne the two voltagers not to be A and -A i need them to be A and B second i need to do that using thyristor
 
With a voltage divider, you can get A and B to be any posivite value you want between the positive and negative terminals of your battery. Then use these values as inputs to a couple of op-amps used as comparators. You should then be able use the comparator outputs to find a way to switch your charger on/off while using thyristors.
 
well it is a good idea but i canot use op amps sorry for wasting ur time any other ideas . i just can use thyristor diodes and resistors
