Ideal gyrator in electrical systems
Gyrators can be used to implement an inductor with a capacitor. The main benefit is that an equivalent inductance can be created with a much smaller physically sized capacitance. In practice, a gyrator is implemented with an op-amp plus additional passive components.
The Gyrator block models an ideal gyrator with no losses, described with the following equations:
|Current flowing into the input + terminal|
|Current flowing out of the output + terminal|
The two electrical networks connected to the primary and secondary windings must each have their own Electrical Reference block.
Use the Variables tab in the block dialog box (or the Variables section in the block Property Inspector) to set the priority and initial target values for the block variables prior to simulation. For more information, see Set Priority and Initial Target for Block Variables.
The gyration conductance constant G. The
default value is
The block has four electrical conserving ports. Polarity is indicated by the + and – signs. Ports labeled +1 and –1 are connected to the primary winding. Ports labeled +2 and –2 are connected to the secondary winding.
