Abstract
A method of simulating the electrical behavior of an ideal transformer. The representation of the ideal transformer is frequency independent and can be used to simulate the behavior of an ideal transformer over the frequency range from DC to infinity. In one embodiment, the ideal transformer is represented as having an input sub-circuit and an output sub-circuit. Each sub-circuit includes a resistor connected in parallel across a current controlled current source. The input current, output current, current sources, and resistances are scaled by a scaling factor representing the turns ratio between the primary and secondary windings of a physical transformer. In the present invention, the current sources are responsible for the current scaling and the resistors are responsible for the impedance scaling. The circuit elements of the representation may be used as the basis for generating a set of input parameters for a circuit emulation program.
