Purpose
Single-phase transformer with winding resistance and optional core loss
Library
Electrical / Transformers
Description
This transformer models three coupled windings on the same core. The
magnetization inductance and the core loss resistance
are modeled as
linear elements. Their values are referred to the primary side. A stiff solver is
recommended if
is not infinite.
The electrical circuit for this component is given below:
In the transformer symbol, the primary side winding is marked with a little circle. The secondary winding is marked with a dot at the outside terminal, the tertiary winding with a dot at the inside terminal.
Parameters
- Leakage inductance
- A three-element vector containing the leakage inductance of
the primary side
, the secondary side
and the tertiary side
. The inductivity is given in henries (H).
- Winding resistance
- A three-element vector containing the resistance of the
primary winding
, the secondary winding
and the tertiary winding
, in ohms (
).
- No. of turns
- A three-element vector containing the number of turns of the
primary winding
, the secondary winding
and the tertiary winding
.
- Magnetization inductance
- The magnetization inductance
, in henries (H). The value is referred to the primary side.
- Core loss resistance
- An equivalent resistance
representing the iron losses in the transformer core. The value in ohms (
) is referred to the primary side.
- Initial current
- A three-element vector containing the initial currents on the
primary side
, the secondary side
and the tertiary side
, in amperes (A). The currents are considered positive if flowing into the transformer at the marked terminals. The default is [0 0 0].
