Method Details

getCurrent

public Real getCurrent(Real voltage,
 Real dt)

Description copied from interface: CircuitComponent

Calculates the current flowing through the component given the voltage across it.

Specified by:

getCurrent in interface CircuitComponent

Parameters:

voltage - Voltage across the component (Volts)

dt - Time step (Seconds) - used for dynamic components

Returns:

Current (Amperes)

getCapacitance

public Real getCapacitance()

reset

public void reset()

Description copied from class: CircuitElement

Resets the element to initial state.

Overrides:

reset in class CircuitElement

startIteration

public void startIteration()

Description copied from class: CircuitElement

Called at the start of each simulation iteration. Used for time-dependent elements to update their state.

Overrides:

startIteration in class CircuitElement

stamp

public void stamp()

Description copied from class: CircuitElement

Stamps the element's contribution into the circuit matrix. This is called once during circuit analysis to build the MNA matrix. Linear elements stamp constant coefficients; nonlinear elements stamp initial guesses that will be updated in CircuitElement.doStep().

Specified by:

stamp in class CircuitElement

doStep

public void doStep()

Description copied from class: CircuitElement

Performs one simulation step for this element. Called during each iteration of the solver. Nonlinear elements update their matrix contributions here.

Overrides:

doStep in class CircuitElement

calculateCurrent

public void calculateCurrent()

Description copied from class: CircuitElement

Calculates the current through this element. Called after node voltages are updated.

Overrides:

calculateCurrent in class CircuitElement
