Abstract:In order to achieve DC voltage matching, on-board charging, and DC/AC power inversion, three independent power converters are often needed in traditional Distributed Power Converter (DPC) systems of electric vehicles (EVs): bidirectional DC/DC (Bi-DC/DC), AC/DC, and DC/AC. The requirement of electronic devices such as power switches, inductors, and capacitors make the converter costly and complicated in structure. In this paper, a power converter with multi-operating mode (PCMM) is presented. The proposed PCMM can work in Bi-DC/DC, AC/DC, and DC/AC modes. The state-space averaging model of PCMM considering resistance of Insulated Gate Bipolar Transistor (IGBT) and the inductor is presented. Based on this model, the transfer function of the system is derived and the controller is designed. The simulation and experimental results show that PCMM can meet the design target and verify the feasibility of the model. The measurement results show that the weight of PCMM proposed in this paper is reduced by 51.2% compared with the traditional structure.

In order to enhance the stability of single-phase microgrid, virtual synchronous generator (VSG) control method is investigated in this paper. Its electromagnetic model and electromechanical model are established to illustrate the performance of VSG. Considering the 2nd fluctuation of fundamental-frequency in the output power, an instantaneous power calculation strategy is proposed based on the intrinsic frequency of single-phase VSG. Besides, a virtual power calculation method is presented to achieve islanded/grid-connected seamless transition. Stability analysis and comparison simulation results demonstrate the correctness of the presented power calculation method. At last, the effectiveness of the proposed approach is verified by comparison experiments of islanded/gridconnected operations in a 500 VA single-phase inverter.

“…A two-degree-of-freedom (DOF) controller is utilized for a DG-based system as an uninterruptible power supply (UPS) to keep the voltage of AC bus at the desired value in presence of the stochastic behaviour of the loads [17]; this proposed DG model demonstrates a smooth transition from the grid-connected mode to the islanded mode. In [18][19], a control strategy is proposed based on the spatial repetitive controller (SRC) that utilizes the Lyapunov direct method to control the power consumption of the loads, maintaining the load voltage at the reference value. A switching pattern is proposed in [20] that is based on the space vector pulse width modulation (SVPWM) and controls a single stage current source boost inverter in order to achieve a desired frequency and voltage magnitude for both the islanded and grid-connected modes.…”
