Semi-conductor components: command mode

Command signal

The command mode is a dependence f(t) that can be a function:

  • defined by the user (formula)
  • crenel

Crenel function

The crenel function is a function that defines a crenel. It is presented in the figure below.

  • T is the period
  • Ton is the turn on time
  • Toff is the turn off time

Switch example

The Switch component is a semi-conductor component controlled at the opening and at the closing, independent of the condition at its terminals.

An example of the R(t) characteristic of a switch is presented in the figure below.

  • T is the period
  • Ton is the turn on time
  • Toff is the turn off time
  • Ron is the on state resistance
  • Roff is the off state resistance
