“…Each g-gyrator has a sliding-mode regulation loop, which consists of an analogue multiplier, a hysteretic comparator, and an operational amplifier-based linear circuit to induce a sliding regime in the BIF converter characterized by equation I 2i = g i V gi , where I 2i and V gi are, respectively, the dc values of output current and input voltage of gyrator i (i = 1, 2, 3), and g i is the gyrator conductance. The stability of the sliding regime is guaranteed by the damping series network R d C d connected in parallel with the input filter capacitor and by the damping paralleled network con- nected in series with the input filter inductor [7]. The r-gyrator, in turn, has a sliding-mode regulation loop with the same elements like the g-gyrator, thus yielding the output dc bus voltage given by V 2 = rI 2T , where r is the gyrator resistance.…”

Basic configurations employed in the design of power architectures can be efficiently implemented by means of power gyrators. A modular architecture for a dc bus based on the connection of N g-gyrators and one r-gyrator is proposed to perform source splitting and achieve voltage regulation. Source splitting can provide high power, and it is implemented by paralleling the N output ports of the g-gyrators whose corresponding input ports are excited by independent voltage sources. Output voltage regulation is provided by the r-gyrator stage, which is connected in cascade with the source splitting configuration. Experimental results in an 80-W prototype are in good agreement with the theoretical predictions.

“…The proposed circuit, including the proposed stability network, is shown in Figure 3. The analysis of the BIF G-type gyrator controlled by means of a sliding control loop shows that the system must meet a series of inequalities or conditions to obtain the necessary stability of the circuit; in particular [4]:…”

This paper provides a classification of high efficiency switching power-gyrator structures and their use as cells for energy processing in photovoltaic solar facilities. Having into account the properties of these topologies presented in the article, their inclusion in solar facilities allows to increase the performance of the whole installation. Thus, the design, simulation and implementation of a G-type power gyrator are carried out throughout the text. In addition, in order to obtain the maximum power from the photovoltaic solar panel, a maximum power point tracking (MPPT) is mandatory in the energy processing path. Therefore, the practical implementation carried out includes a control loop of the power gyrator in order to track the aforementioned maximum power point of the photovoltaic solar panel.

“…MPPT based on a semigyrator structure From a circuit standpoint, a power gyrator is a two-port structure characterized by any of the following two sets of equations T gV= (1) 12 =gv V1 = rI2 V2 = rI where II, V1 and I2, V2 are DC values of current and voltage at input and output ports respectively and g (r) is the gyrator conductance (resistance) [6,7]. The gyrator is realised by imposing equations (1) or (2) at the ports of a switching converter by the insertion of an appropriate feedback control which can operate at variable or fixed switching frequency [6,7].…”

“…The gyrator is realised by imposing equations (1) or (2) at the ports of a switching converter by the insertion of an appropriate feedback control which can operate at variable or fixed switching frequency [6,7]. Depending on which type of equation is imposed, the power gyrators can be classified in two families: power gyrators of type G (realisation of one of the conductance equations) and power gyrators of type R (realisation of one of the resistance equations) [7].…”

The utilization of solar energy can be made by photovoltaic (PV) cells to generate electric power directly and solar thermal (T) panels can be applied to generate heat power. When the utilization of the solar energy is necessary to generate electric power, the option of using T panels in combination with some heat/ electric power conversion technology can be a viable solution. The power generated by utilizing the solar energy absorbed by a given area of solar panel can be increased if the two technologies, PV and T cells, are combined in such a way that the resulting unit will be capable of co-generation of heat and electric power. In the present paper combined Photovoltaic / Thermal panels are suggested to generate heat power to produce hot water, while the photovoltaic part is used to obtain electric power mainly for covering the electric power consumption of the system, to supply the electronic control units and to operate pump drives etc. Ac and dc supplies are provided by converters for covering selfconsumption and possibly the need of some household appliances. The development and design of the system is made by extensive use of modeling and simulation techniques. In the paper a part of the simulation studies, carried out to determine the energy balance in the electric energy conversion section of the system and the control structure, assuming stand-alone operation is presented.
