A new approach to efficient gyrator realization is described. The approach was motivated by the observation that a A/4 segment of transmission line exhibits gyrator-like behavior. A gyrator that operates at low-frequency band, including dc, is formed by the combination of a A/4 segment of transmission line and a switching network. Using a switching bridge, the lowfrequency signal is converted into a high-frequency wave which is applied to the input terminals of the transmission line. Then the original waveform is reconstructed using a second switching bridge. Since the switching bridge, as well as the transmission line, are loss free (in principle), the resulting gyrator is also lossless. Such a gyrator can find applications in power processing circuits. A circuit based on this approach was constructed and tested at the energy conversion laboratory, Tel-Aviv University, Israel.
