ModelingToolkitStandardLibrary: Electrical Components

Electrical Utilities

ModelingToolkitStandardLibrary.Electrical.OnePortFunction
OnePort(; name, v_start=0.0, i_start=0.0)

Component with two electrical pins p and n and current i flows from p to n.

States:

  • v(t): [V] The voltage across component p.v - n.v
  • i(t): [A] The current passing through positive pin

Parameters:

  • v_start: [V] Initial voltage across the component
  • i_start: [A] Initial current through the component

Connectors:

  • p Positive pin
  • n Negative pin
ModelingToolkitStandardLibrary.Electrical.DigitalPinFunction
DigitalPin(; name)

A pin in a digital circuit.

States:

  • v(t): [V] The voltage at this pin
  • i(t): [A] The current passing through this pin
  • val(t): The binary value of the pin at this point. A voltage from 0V to 0.8V is a binary value of 0.

A voltage in the range 2.0V to 5.0V is 1. Any other value is X.

Analog Components

ModelingToolkitStandardLibrary.Electrical.CapacitorFunction
Capacitor(; name, C)

Creates an ideal capacitor.

States:

  • v(t): [V] The voltage across the capacitor, given by D(v) ~ p.i / C

Connectors:

  • p Positive pin
  • n Negative pin

Parameters:

  • C: [F] Capacitance
  • v_start: [V] Initial voltage of capacitor
ModelingToolkitStandardLibrary.Electrical.IdealOpAmpFunction
IdealOpAmp(; name)

Ideal operational amplifier (norator-nullator pair). The ideal OpAmp is a two-port. The left port is fixed to v1 = 0 and i1 = 0 (nullator). At the right port both any voltage v2 and any current i2 are possible (norator).

States:

See TwoPort

Connectors:

  • p1 Positive pin (left port)
  • p2 Positive pin (right port)
  • n1 Negative pin (left port)
  • n2 Negative pin (right port)

Analog Sensors

ModelingToolkitStandardLibrary.Electrical.CurrentSensorFunction

CurrentSensor(; name)

Creates a circuit component that measures the current flowing through it. Analogous to an ideal ammeter.

States:

  • i(t): [A] Current through the sensor

Connectors:

  • p Positive pin
  • n Negative pin
ModelingToolkitStandardLibrary.Electrical.VoltageSensorFunction

VoltageSensor(; name)

Creates a circuit component that measures the voltage across it. Analogous to an ideal voltmeter.

States:

  • v(t): [V] The voltage difference form positive to negative pin p.v - n.v

Connectors:

  • p Positive pin
  • n Negative pin
ModelingToolkitStandardLibrary.Electrical.PowerSensorFunction

PowerSensor(; name)

Combines a VoltageSensor and a CurrentSensor to measure the power being consumed by a circuit.

States:

Connectors:
