This paper proposes a single-stage three-port isolated H-bridge inverter. Five operating modes and five switching equivalent circuits of the inverter are studied, and three H-bridge three-phase-shift modulation strategy and multi-loop energy management control strategy are proposed to achieve the maximum power tracking of the photovoltaic cells, at the same time, the energy flow and power balance between the three ports of photovoltaic, battery and load are realized by reasonably controlling the charging and discharging of the battery, so as to ensure the continuous and stable power supply of the system to the load. The circuit topology, operation modes, switching equivalent circuits, phase-shift modulation strategy and control strategy, and circuit parameter design of the inverter are also theoretically analyzed. On this basis, a single-stage three-port isolated H-bridge inverter experimental prototype is designed and developed, and the experimental results verify the feasibility and correctness of the proposed topology and control strategy.

Abstract ：
It is difficult to take into account the second-order current ripple, common-mode (CM) current, and efficiency of the converter in the application of vehicle-to-grid (V2G). To address this issue, an asymmetric full-bridge dc-ac converter is presented in this article, which can realize single-stage conversion by multiplexing switches and suppress CM current from the topology principle. A dual-target control strategy for this converter is proposed to implement bidirectional power transmission and power decoupling. Through power decoupling the dc port secondary ripple is transferred to the dc bus capacitor voltage. Besides, the circuit topology, control strategy, operation principle, high-frequency switching process, key circuit parameters design, and losses are analyzed theoretically. A 250 W prototype is built to verify the theoretical analysis. Based on the experimental results, the efficiency is 92.21% while the secondary ripple current of dc port is less than 3% and the common mode leakage current is almost zero at rated power. Finally, the proposed converter system is compared with other research solutions, and the experimental results indicate that the converter system has the optimal comprehensive performance.

Abstract ：
In order to evaluate the feasibility of steel slag powder as filler, the coating properties of steel slag and limestone aggregate were compared by water boiling test, the micro morphology differences between steel slag powder and mineral powder (limestone powder) were compared by scanning electron microscope (SEM), and the high-temperature rheological properties of asphalt mortar with different ratio of filler quality to asphalt quality (F/A) and different substitution rates of mineral powder (S/F) were studied by dynamic shear rheological test. The results show that the surface microstructure of steel slag powder is more abundant than that of mineral powder, and the adhesion of steel slag to asphalt is better than that of limestone. At the same temperature, the lower the ratio of S/F is, the greater the rutting factor and complex modulus will be. In addition, the complex modulus and rutting factor of the asphalt mortar increase with the increase of F/A, and the filler type and F/A have a negligible effect on the phase angle.

In this paper, a new bidirectional DC-AC converter is proposed. The circuit topology of this converter mainly consists of a battery, DC-side filter, energy storage inductor, bus capacitor, asymmetric inverter bridge, AC-side filter and grid, and four circuit modes exist during normal operation. For the application of V2G, a dual-target control strategy is proposed for the converter that can realize bidirectional power transfer and power decoupling, and its circuit topology, control strategy, operating principle and key circuit parameters design are analyzed and studied in depth. The simulation results show that the proposed converter can realize single-stage bi-directional power transfer, with the advantages of simple circuit topology, high quality of grid-connected current waveform and low frequency pulsation of DC-side battery current, which provides a practical new solution for V2G technology. © 2021 IEEE.
