SIMPLORER User Manual V6.0 - FER-a

Nonlinear Two-winding Transformer
SIMPLORER 6.0 — Manual 191
>>Basics>Circuit>Transformers>Single-Phase Systems
The component represents a transformer based on the Spiro model. The characteristic describes
the nonlinear mutual inductance without hysteresis (L=f(I)). L has to be >0 within the
characteristic.
For each coil make sure a network path exists to the ground node. The macro does not provide
an access to the initial value of currents, these are assumed to be zero. Within the dialog you
can define the main and leakage inductances, the equivalent resistances for iron losses and
the winding resistances for each side.
W 2
KTR = ------- with W1 = Windings Primary Side and
W1 =
Windings Secondary Side
