Discussion Overview

The discussion revolves around modifying a circuit to operate three parallel wires in sequence using MOSFETs triggered by a feedback coil. The goal is to create a synchronized pathway where the coils interact through repelling fields, cycling through activation and deactivation to close the circuit with a battery.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant seeks assistance in modifying a circuit to achieve a synchronized operation of three MOSFETs and coils.
  • Another participant suggests that the setup resembles a three-phase inverter and asks for clarification on the purpose of the circuit.
  • A different participant confirms the inverter analogy and mentions the intention to run a self-resonant flyback transformer while controlling the MOSFETs in sequence.
  • One participant proposes using a current sense transformer on the ground side of the flyback to signal when the magnetic field has collapsed, potentially to control the next MOSFET in line.

Areas of Agreement / Disagreement

Participants generally agree on the similarity of the circuit to a three-phase inverter, but there is uncertainty regarding the feasibility and complexity of running the MOSFETs in sequence with a flyback transformer. The discussion remains unresolved with multiple competing views on the approach.

Contextual Notes

There are limitations regarding the clarity of the circuit's purpose and the specific technical challenges involved in synchronizing the MOSFETs and coils. Assumptions about the operation of the flyback transformer and the triggering mechanism for the MOSFETs are not fully detailed.

Hi People!
I need some help to modify the following circuit to run current trougth three parallel wires in sequence, using three mosfets triggered by one feedback coil.My goal is to obtain a syncronized patway in a manner that when the first coil is shut OFF,the reversing field of the coil have to repel aganist the field of the next coil that is still in the ON phase.Then the second coil is shut off and will repel with the third coil.The last coil (third) will repel aganist a fourth coil that is connected to the ends of all the previous coils to close the circuit with the battery. All these steps have to be done ciclically.It can be done in a simple way?Thank you!

Kind of like a three phase inverter? I am not quite clear on what your trying to do, what is this for?
 
Yeah,its like a three phase inverter. I want to run a self resonant flyback transformer and with the output turn off the gate of other two mosfet,in sequence. Some one has said to me that running in sequence three mosfet with a fwith flybeack is non easy,but I don't believe in...
 
Hmm, my first instinct would tell me to use a current sense transformer on the gnd. side of the flyback to signal when the field has collapsed, perhaps use this signal to control a mosfet driver for the next transformer in line. Am I on the right track here?
