There are lots of issues existed with the Power Supply System in DC Building, and it is controversial as these issues have not been solved completely. In recent years, worldwide attention has been focused on proposing the standards of “HVDC power supply system” or “up to 400Vdc power feed system” following with the development of the power supply system in data center. Many attentions from the worldwide research organizations or institutions have pointed out that these standards can be applied with DC Building. In this paper, the standards of the main organizations and institutions on HVDC power supply system are introduced. Then some definitions of the issues among the standards of these organizations or institutions are analyzed and compared. The requirements for designing the power supply system in DC Building are discussed based on the above issues, including the system topology and the key power electronic converters interfaced to the system. The analysis can be referenced for designing the equipment of the Power Supply System in DC Building and helpful for popularizing the DC Power Supply Technology.

In this paper, high-efficiency, extremely high step-up and step-down bi-directional DC-DC converter is proposed. The proposed converter consists of a flyback and an isolated switched-capacitor cell to achieve high cost competitiveness for the extreme operation. The output of the flyback converter and that of the isolated switched-capacitor is connected in series to obtain a high voltage step-up. In the reverse direction, then, this converter can be an extremely voltage step-down one. For the design of the controller, the small-signal transfer functions of the converter are derived. Finally, a 100W hardware prototype of the proposed converter is implemented. To improve the efficiency of a PV system employing the proposed converter, a maximum Power Point Tracking (MPPT) method is applied with Perturb and Observe (P&O) method. To demonstrate the operation of the bidirectional converter, the main switch current is used for the power control. All of these controls are implemented with a digital signal processor (DSP).

In this paper, a novel hybrid current balancing method for multi-channel LED drive based on quasi-two-stage converter is proposed. In presented structure, each output modules includes two LED strings and can achieve internal current balancing easily through its current balancing capacitor. The current regulators are used to balance the currents among the output modules. By applying the partial power control, the current regulator can obtain higher efficiency and lower cost due to higher switching frequency. Furthermore, by adopting the active method, the device has better load adaptability and lower voltage stress. Additionally, hybrid structure utilizes the advantages of passive and active method with simpler control. Performance of the proposed scheme is validated by the simulation and experimental results from a 120W prototype with four LED strings.

There is discontinuous input current or output current in most of the isolated DC-DC converter. If continuous current is required, generally we need to add additional bulky filter, which will reduce the system's power density. In this paper, the method of adding a built-in filter to the isolated converter to achieve a continuous input current was employed. The built-in filter is composed of transformer leakage inductor and cross-coupled capacitor. Two kinds of push-pull converters with built-in filter which are derived from the voltage-type push-pull converter are proposed in this paper. The working rules and the results of PSIM simulation are given. A prototype was built in our lab to verify the synthesizing theory. The experimental results have verified the theoretical analysis.

Renewable energy generation is widely used to solve energy shortage and environment problem. Since the output power of the solar cell and the wind turbine will change with the sunlight irradiation and the wind flow, the power of the solar cell and the wind turbine are not stable, so there is a need of a storage equipment connected to the micro-grid system. With the characteristics of high efficient energy storage and quick response to the power exchange, the superconducting magnetic energy storage (SMES) can be used to meet the balance of the micro-grid. This paper proposes an improved control strategy combing SMES and micro-grid. A SMES and micro-grid system are connected together with the AC bus. A detailed model of the hybrid system is built with MATLAB/SIMULINK. Simulation results with and without SMES connected to the grid-connected photovoltaic system are presented, compared, and analyzed. The results of simulation demonstrate that the SMES system can maintain the grid side power as a constant value which can contribute to the stability and reliability of the micro-grid system.

The purpose of this paper is to present the speed-sensorless weighted vector control method of parallel-connected dual induction motors fed by a single inverter. In this paper, the flux linkage of dual induction motors is reoriented, and then the control expressions of weighted rotor flux linkage and weighted torque of dual motors are derived. The weight value of vector control for dual induction motors in unbalanced load is distributed automatically according to the real-time torques. The parameters of each motor, namely rotor flux, and speed were estimated using q-axis flux observers to achieve sensorless control. The validity and effectiveness of the presented method was demonstrated through simulations and experiments.

Permanent magnet synchronous motor (PMSM) are favored in traction drives of rail vehicles for their high efficiency of operation. Traction inverters always operate at reduced switching frequency to minimize the losses in semiconductor devices. To restrain the motor current harmonics, off-lined calculated optimal synchronous pulse patterns can be used. This paper presents a closed-loop control of permanent magnet synchronous motor traction drives operated with optimal synchronous pulse patterns. The optimization problem was stated based on the minimization of the rms value of the phase current harmonics. And the optimum solutions of the problem were given. Then the relationships between the optimum pulse patterns and their corresponding optimum stator flux linkage trajectory were analyzed. By forcing the stator flux linkage vector to follow this optimum trajectory, a closed-loop vector control of PMSM was proposed. Using the simulation and experimental results, this paper elaborates on the steady-state operating modes for employing various pulse patterns and the transition of different pulse patterns during the dynamic operations. The results validate the proposed control strategy.

This paper proposes a novel control strategy-Coordinated DC Voltage Control (CDVC)-to enhance the AC fault ride through capability of Multi-terminal HVDC system. It is able to keep DC voltage constant and distribute power fast and smoothly, independent on line impedance parameters. Combined with this original control strategy, a series of AC fault ride through methods, including voltage reduction, frequency increase and DC chopper methods are applied to avoid overvoltage of HVDC lines. Compared with the conventional voltage droop control, the proposed CDVC strategy can keep DC voltage at rated value on different conditions and make full use of active power by adjusting power distribution ratio during fault periods. The control effect is validated in two scenarios by a five-terminal HVDC system based on PSCAD/EMTDC.

In this paper, a high voltage SiC MOSFET module with series-parallel hybrid topology is presented and analyzed. The module consists of two uniform parts in parallel and each of the part includes three sub-parts in series. The sub-part contains three primary parts connected in string where each of these parts has a parallel of two SiC MOSFETs. These SiC MOSFETs are divided into six sub-modules, which are driven by a common driving signal. A 10kV/200A SiC MOSFETs module is fabricated based on this hybrid topology with thirty-six 1200V/40A SiC MOSFET chips. The dynamic switching behavior of the module is tested and analyzed at 5400V/200A with a switching speed of 440ns in turn-on process and 250ns in turn-off process.
