Abstract

Two types of gyrators that can be used for controlling the energy transfer between two sub networks are analyzed in this paper. The first one operates time-continuously and is implemented using a LM 13700 operational transconductance amplifier (OTA). Under PSpice simulation and experimentally gathered data the antireciprocity of this gyrator has been verified. The main advantage of this realization is that the energy flow from one port to the other can be simply controlled by modifying the bias currents of the OTAs. The second type is a commutation-operated double-bridge DC-DC converter. The energy flow in this case can be easily controlled by modifying the switching delay of between the bridges.
