Electrical description

Introduction

The fourth stage corresponds to the electrical description of the conductors. That means the description of the electric environment (electrical scheme), as well as the electric connections among the different conductors.

Application

The electric circuit described depends on the selected application:

Supplied conductors or Conductors impedance.

Supplied conductors application

Conductors impedance application

It is necessary to define at least one supply source and possibly passive components or loads

It is necessary to define at least one impedance probe and possibly passive components or loads

Electrical circuit

The electrical circuit is made of:

  • unidirectional and bidirectional conductors previously described
  • complementary components (sources, passive component, probe)
  • connections between these circuit components (connections are carried out via the terminals)

Whatever the quantities seeked are (currents or equivalent impedances), it is necessary to have closed current loops.

Components

The available components for the two Flux PEEC computation types are presented in the table below.

Supplied conductors application Conductors impedance application
  • Sources: current source, voltage source
  • Passive components: resistance, inductance, capacitance
  • Impedance probe: component for impedance measurement between two points of the circuit
  • Passive components: resistance, inductance, capacitance

Terminals

Terminals, defined with respect to the conductors, allow connections. They are presented in the table below.

Unidirectional conductor: (the terminals are automatically created with the conductor geometry)

geometric tube conductor a tube point = a terminal
CAD geometry conductor input / output faces must be defined by the user

Bidirectional conductor: (the terminals are created after the conductor geometry)

Points or faces defined by the user

Connections

The connections between the conductors are carried out via the terminals.

An example of connection between two conductors is presented in the figure below.
