Description
Block Three-Winding Transformer (CE) simulates three connected windings in an RF signal simulation environment.
The block implements the relations
where
-
, and — inductance;
-
— mutual inductance between - th and -th windings with coupling coefficient ;
-
, and — voltage at the terminals of the windings at a time ;
-
, and — currents through the windings at a time . The block uses standard dot notation to indicate the direction of the positive current relative to the positive voltage.
Library current and voltage signals RF Blockset they consist of a common - mode ( ) and quadrature ( ) components at each frequency specified in the block Configuration:
