Abstract:
A method of simulating the electrical behavior of a transformer in an electrical circuit, the transformer having a primary winding port coupled between a first node and a second node of the electrical circuit, and a second winding port coupled between a third node and a fourth node of the electrical circuit, said method comprising the steps of:simulating a first resistor coupled between the first and second nodes; simulating a second resistor coupled between the third and fourth nodes; simulating a first current-controlled current source (CCCS) coupled between the first and second nodes, the current flowing through said first CCCS from the first node to the second node plus the current flowing through said first resistor from the first node to the second node being denoted as current IIN and being capable of having a non-zero value; and simulating a second current-controlled current source (CCCS) placed between the third and fourth nodes, said second CCCS generating a current which is related to current IIN, the current flowing through said second CCCS from the third node to the fourth node plus the current flowing through said second resistor from the third node to the fourth node being denoted as current IOUT and being capable of having a non-zero value; wherein said first CCCS generates a current which is related to the current IOUT.
