Modelica.Electrical.Analog.Semiconductors

Semiconductor devices such as diode, MOS and bipolar transistor

Information

This package contains semiconductor devices:

• diode
• MOS transistors
• bipolar transistors
• thyristor
• triac

Most of the semiconductor devices contain a conditional heat port, which is not active by default. If it is active the loss power is calculated to be used in a thermal net. The heating variants of the semiconductor devices are provided to use the thermal port temperature in the electric calculation. That means that for a true thermal electric interaction the heating device models have to be used.

Simple diode

Information

The simple diode is a one port. It consists of the diode itself and an parallel ohmic resistance R. The diode formula is:

                v/vt
  i  =  ids ( e      - 1).

If the exponent v/vt reaches the limit maxex, the diode characteristic is linearly continued to avoid overflow.

Please note: In case of useHeatPort=true the temperature dependence of the electrical behavior is not modelled yet. The parameters are not temperature dependent.

Modelica.Electrical.Analog.Semiconductors.Diode2

Improved diode model

Information

This diode model Modelica.Electrical.Analog.Semiconductors.Diode2 is an improved version of the existing diode model Modelica.Electrical.Analog.Semiconductors.Diode. In includes a series resistance, parallel conductance, and also models reverse breakdown. The model is divided into three parts:

• lower half of reversed bias region including breakdown: -Ids·(exp(-(vd+Bv)/(N·Vt)) + 1 - 2·exp(-Bv/(2·N·Vt)))
• upper half of reverse biased region and forward biased region before conduction: Ids·(exp(vd/(N·Vt)) - 1)
• forward biased region after conduction: iVdMax + (vd - VdMax)·diVdMax

Temperature dependent behaviour is modelled when useHeatPort=true. In that case, the Vt parameter is ignored, and Vt is computed as k·T/q, where

• k is Boltzmann's constant
• T is the heat port temperature.
• q is the electron charge.

Modelica.Electrical.Analog.Semiconductors.ZDiode

Zener diode with 3 working areas

Information

The simple Zener diode is a one port. It consists of the diode itself and an parallel ohmic resistance R. The diode formula is:

                v/Vt                -(v+Bv)/(Nbv*Vt)
  i  =  Ids ( e      - 1) - Ibv ( e                  ).

If the exponent in one of the two branches reaches the limit Maxexp, the diode characteristic is linearly continued to avoid overflow.

The Zener diode model permits (in contrast to the simple diode model) current in reverse direction if the breakdown voltage Bv (also known Zener knee voltage) is exceeded.

The thermal power is calculated by i*v.

Please note: In case of useHeatPort=true the temperature dependence of the electrical behavior is not modelled yet. The parameters are not temperature dependent.

Simple MOS Transistor

Information

The PMOS model is a simple model of a p-channel metal-oxide semiconductor FET. It differs slightly from the device used in the SPICE simulator. For more details please care for H. Spiro.

The model does not consider capacitances. A high drain-source resistance RDS is included to avoid numerical difficulties.

Please note: In case of useHeatPort=true the temperature dependence of the electrical behavior is not modelled yet. The parameters are not temperature dependent.

Modelica.Electrical.Analog.Semiconductors.Thyristor

Simple Thyristor Model

Information

This is a simple thyristor model with three pins: Anode, Cathode and Gate. There are three operating modes:conducting, blocking and reverse breakthrough.
As long as the thyristor is in blocking mode it behaves like a linear resistance Roff=VDRM^2/(VTM*IH). But if the voltage between anode and cathode exceeds VDRM or a positive gate current flows for a sufficient time the mode changes to conducting mode. The model stays in conducting mode until the anode current falls below the holding current IH. There is no way to switch off the thyristor via the gate. If the voltage between anode and cathode is negative, the model represents a diode (parameters Vt, Nbv) with reverse breakthrough voltage VRRM.

The dV/dt switch on is not taken into account in this model. The gate circuit is not influenced by the main circuit.

This is a simple TRIAC model based on the extended thyristor model Modelica.Electrical.Analog.Semiconductors.Thyristor.
Two thyristors are contrarily connected in parallel, whereas each transistor is connected with a diode.
Further information regarding the electrical component TRIAC can be detected in documentation of the ideal TRIAC model.
As an additional information: this model is based on the Modelica.Electrical.Analog.Semiconductors.Thyristor.

Attention: The model seems to be very sensitive with respect to the choice of some parameters (e.g., VDRM, VRRM). This is caused by the thyristor model. Further investigations are necessary.
