Inventor: KOBAYASHI HIROYOSHI
IPC: G06F17/50
Filed: 2017-03-23
Abstract: PROBLEM TO BE SOLVED: To provide an equivalent circuit that is capable of accurately expressing superposition characteristics with a simple structure and is excellent in practicality and workability.SOLUTION: A current sensor 22 and a voltage source 24 are connected in series between external terminals of an equivalent circuit 20. A reference state element 26 of an impedance Z constitutes a closed loop with a current source 28. The reference state element 26 is an equivalent circuit of the impedance element at the time of no current overlapping. When current I flowing through the equivalent circuit 20 is detected by the current sensor 22 and is reproduced by the current source 28 of the closed loop circuit and applied to the reference state element 26, a potential difference V(0) is generated across the reference state element 26. A voltage obtained by multiplying the potential difference V(0) with a correction coefficient G is output by the voltage source 24 connected in series to the current sensor 22. By making the correction coefficient G dependent on the current I or the inter-terminal voltage V, the impedance Z indicated by the equivalent circuit 20 can be reproduced as a characteristic depending on the current I or the inter-terminal voltage V.SELECTED DRAWING: Figure 1
