LC circuits in series with Diodes

Click For Summary

Discussion Overview

The discussion revolves around the behavior of LC circuits in series with diodes, particularly focusing on the charging and discharging sequence of capacitors when a switch is closed. Participants explore theoretical implications, circuit design, and potential applications, including the effects of inductance and diode orientation.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Mathematical reasoning
  • Experimental/applied

Main Points Raised

  • Some participants question whether the charged capacitor will charge both Capacitors B and C simultaneously or sequentially, considering the impedance of the inductors.
  • There is a suggestion that if the first capacitor is charged correctly, it should allow current to flow through the diode while discharging.
  • Some participants express uncertainty about the implications of the schematic orientation and its effect on circuit behavior.
  • One participant proposes that the circuit may require switching elements to achieve the desired energy transfer without settling into an equilibrium state.
  • Others argue that energy can split and flow in parallel branches, challenging the notion that energy must move in one direction at all times.
  • There is a discussion about the potential need for differential equations to analyze the circuit behavior, with some participants indicating a lack of familiarity with these methods.
  • One participant mentions the possibility of using AC signals at the resonant frequency of each LC segment to achieve specific outcomes.
  • Concerns are raised about diode drops and losses affecting the voltage across subsequent capacitors.
  • Some participants suggest simulating the circuit to better understand its behavior under various conditions.

Areas of Agreement / Disagreement

Participants express multiple competing views regarding the charging sequence of the capacitors, the necessity of switching elements, and the overall circuit behavior. The discussion remains unresolved with no consensus on the best approach or understanding of the circuit dynamics.

Contextual Notes

Limitations include the participants' varying levels of familiarity with circuit analysis techniques, such as KCL and KVL, and the potential impact of non-ideal components on circuit performance. The discussion also highlights the dependence on schematic orientation and assumptions about initial conditions.

Who May Find This Useful

This discussion may be useful for individuals interested in circuit design, particularly those exploring the dynamics of LC circuits, diode behavior, and energy transfer mechanisms in electrical engineering applications.

I want an apparatus that I can experiment with. I am most interested in; the wave nature the capacitors will charge with, the momentum of the moving charges, thermal coefficient of resistance. Basically, an analog of em waves that have acceptable wavelength without producing harmful radiation. It is ideal if I can keep the time between input pulses long.
