Linear 2-Winding Transformer PLECS 1.5 Online Help Linear 2-Winding Transformer Purpose Two-winding transformer. Library Passive Components Description This transformer models two 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 side winding is marked with a dot. Parameters and Dialog Box Leakage inductance A two-element vector containing the leakage inductance of the primary side and the secondary side . The inductivity is given in henries (H). Winding resistance A two-element vector containing the resistance of the primary winding and the secondary winding , in ohms (). Winding ratio The ratio between the number of turns of the primary and secondary 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 two-element vector containing the initial currents on the primary side and the secondary side , in amperes (A). The currents are considered positive if flowing into the transformer at the marked terminals. The default is [0 0].
