SIMPLORER 6.0 — Manual 85
� «Time Controlled»
The predefined time-controlled voltage source is selected. In the list, select a time function
and define the corresponding parameters. These are Common parameter types. Enter a numerical
value, a variable, or an expression in the text box. See also “Separate Component
Characteristic” on page 297.
� In the list, select the sine, pulse, triangular, trapezoidal, saw-tooth rising, or saw-tooth falling
time function.
� � «Spice Compatible»
If the box is checked, the spice compatible reference arrow system is applied to the source.
AC Parameters
� «Phase & Magnitude»
The Phase/Magnitude representation is selected. Common parameter types. Enter a numerical
value, a variable, or an expression in the text box. See also “AC Simulation Models” on
page 401.
� «Angular Dimension»
In the list, select radians or degrees for the angular dimension of the phase.
� «Real & Imaginary»
The Real/Imaginary representation is selected. Common parameter type. Enter a numerical
value, a variable, or an expression in the text box.
Linear Voltage Source
vt () =
– EMF
The value of the electromotive force (EMF) is equivalent to the present value of the quantity
specified in the text box. Usually a constant value, a time function, or a variable are chosen,
or the value of the electromotive force is determined in a state graph. All system quantities
and variables can be combined with mathematical and logical operators and constants.
However, the expression must be technically meaningful. If it is not, numerical instability or
completely wrong results are possible. In particular, sudden changes in the first derivation of
the control quantity should be avoided.
The SIMPLORER voltage sources have the opposite orientation compared to SPICE-like voltage
sources. See also “Load Reference Arrow System of Circuit Components” on page 71.
The current through an ideal voltage source can be arbitrary. Real voltage sources have always
an internal resistance. If the internal resistance is essential for the simulation target, a
corresponding resistance must be connected in series.
