Switch and semi-conductor components: overview

Introduction

The semi-conductor components are of four types:

• the switch
• the diode

Utilization

The semi-conductor components switch, diode are available only in transient applications .

In fact, it deals with the commanded components, and their state (on, off) is time dependent.

Overview

In a general way the semi-conductor components are defined by:

• a current-voltage characteristic
• a command mode

Two models are available for this characteristic:

• Ron-Roff model
• Exponentiel model

These two models are described in the following paragraph (§ Semi-conductor components: diode model ).

The semi-conductors components are presented in the table below.
