“…It is found that the efficiency of the proposed topologies is quite comparable with others. Table 6 shows that the of BDHC [35], CFSI [29], and hybrid buck-boost converter [34] are less than that of the proposed topologies. Two converters IHC [32] and minimum phase dual output converter [33] show higher efficiency than that of the proposed topologies.…”

In this paper, two (series and parallel versions) quasi Z source inverter (qZSI)-based multioutput series-parallel topologies capable of supplying multiple three-phase AC and single boost DC outputs simultaneously are presented. The proposed parallel version topology can supply n number of AC outputs along with one boost DC with constant voltage and variable current. Similarly, the series version topology can give n number of AC including one boost DC output with constant current and variable voltage. The outputs of the proposed topologies can feed directly to DC/AC microgrids and multiple residential loads simultaneously without using any extra adapter/regulator and thereby avoiding local power conversion to meet the load demand. A hybrid pulse width modulation technique with constant frequency is used to operate the proposed topologies. The performance of the proposed topologies is verified by developing the prototypes of 2.18 kW (for parallel version) and 2.02 kW (for series version) for two three-phase AC outputs and one boost DC output. The developed prototypes show measured efficiency of 90.01% for the parallel and 89.95% for the series version topology.

“…Therefore, scholars have proposed a variety of non-isolated Buck-Boost circuits. Shiluveru [3] added q-ZSC(quasi-Z-source converter) topology to traditional Buck-Boost converter, which can realize power conditioning with improved reliability along with inherent shoot-through protection capability. Li [4] introduced soft-switching units to the control of Buck-Boost converter, whose results indicate that it can effectively reduce switching losses.…”

Proton Exchange Membrane Fuel Cell (PEMFC) is difficult for application because of its high current and wide voltage output. A fractional order PID controller is introduced to a Four-Switch Buck-Boost DC/DC converter to stabilize the power output in this paper. To reduce the inductor current ripple, a kind of dual-triggered switch strategy is employed in detail, and an accurate dynamic model of DC/DC converter is proposed for fuel cell measurement and control system. Then a fractional order PID controller is designed for voltage module compensation, in which a stochastic inertia weight PSO algorithm is employed to optimize the parameters of this controller. The results of simulation and experiment indicate that the compensation effect of fractional order PID controller has better performance than the integer order controller, which is robust to the variation of fuel cell system dynamics and power request.
