Hybrid Construction Machinery differs from conventional Hybrid and Full Electric Vehicles since the electrification can be applied not only to the traction system, but also and mainly to its attachments, which generally are the major responsible for diesel consumption. A dc-dc converter stage is usually applied between the battery bank and the motor drive in order to properly deal with the substantial battery voltage variation as a function of its state-of-charge (SoC). This work presents how a field weakening strategy can be applied to a Permanent Magnet Synchronous Machine (PMSM) drive in order to allow direct connection of the batteries to its dc link, therefore suppressing the need of a dc-dc stage and, consequently, reducing the hybridization costs, weight and volume. Simulation results are presented in a ditch excavation cycle.

The optimal sizing of on-board and wayside energy storage systems in urban rail transit, considering the effect of regenerative braking energy recovery, is studies in this paper. Firstly, the original braking resistors are replaced by on-board energy storage systems with the constraints of weight and volume. Then to evaluate the trade-off between component cost and operational cost, an optimization problem, which integrates sizing and energy management of on-board and wayside energy storage systems, is introduced and formulated in terms of daily cost. Finally, a case study of Batong Line in Beijng is carried out to validate the above proposed approach and Gurobi is applied to obtain a computationally tractable solution for the model. Results show the effectiveness of the optimal model.

Solid-state transformer (SST) based super charge station (SPS) have become an attractive substitute for state-of-the-art charge stations because of their high efficiency, high power density, and convenient maintenance and power expansion However, compared to traditional SPS system which is connected to MV grid with a bulky line frequency transformer, SST is more fragile to failure because that it directly connects to the MV grid. Different kinds of surge events would be seen in the MV grid, among which lightning is one of the most serious scenarios. Therefore, the lightning influence on the Metal Oxide Arrester (MOA) clamped floating SST is modeled and analyzed. The modeling process of such an SST system, including the lightning wave and MOA, is shown. Evaluation results show that voltage stress between phases would hugely increase during the lighting, and this effect can be eliminated by MOA connected between phases.

Three-phase voltage source inverters (VSIs) have been widely used in renewable energy conversion and motor drives, etc. However, dead-time, which is inevitable to prevent shoot-through of VSI in-phase legs, causes output fundamental voltage loss and low-order harmonic increases. In this paper, six short side non-zero voltage base vectors are found beside the six long side non-zero voltage base vectors in conventional space voltage vector plane when dead time is considered, which is not proposed previously. Then, by considering the amplitude and phase angle of twelve non-zero voltage base vectors, a dead time compensation (DTC) strategy for voltage integrity based on a complete switching state is proposed. Finally, both simulations and experiments are carried out based on the open-loop control to verify the effect of the proposed compensation strategy.

In this paper, the optimization method of single-segment velocity trajectory of high-speed train is studied. The optimization process is divided into two stages. Firstly, the energy consumption and travel time are used as the optimization criteria; then the section is divided into several subsections according to different speed constraints, and the optimal speed trajectory search strategy under different track characteristics is proposed. Secondly, talking the speed sequence corresponding to the transition point of the train running state in different sub-intervals as the decision variable, the model in this paper adopts a hybrid algorithm based on multi-objective particle swarm combined with NSGA-II (Non-dominated Sorting Genetic Algorithm-II) in order to obtain the Pareto frontier of the train velocity trajectory with the same satisfaction for all targets.

For drive train topologies, it is vital to evaluate the consequences of applying different pulse width modulation (PWM) methods for low energy consumption objects. This paper investigates a Boost Inverter for electric vehicles (EVs) and hybrid vehicles (HVs). Three PWM methods, including space vector PWM (SVPWM), power factor adaptation discontinuous PWM (PFA-DPWM), and $240^{circ} -$clamped PWM (240CPWM), are presented and analyzed in the performance of Boost Inverter. The comparative analysis of switching loss and harmonic distortion shows that the switching loss of 240CPWM was reduced by 86.6% compared with SVPWM at unit power factor and 240CPWM has a similar harmonic distortion factor compared with SVPWM. Simulation results from a permanent-magnet synchronous motor (PMSM) and Boost Inverter drive topology with a variable-voltage control technique are presented. Based on the loss model of SiC MOSFET, the Boost Inverter efficiencies are shown in the form of efficiency maps used to validate the efficiency performance of different PWM methods. The simulation results demonstrate that the 240CPWM shows a higher efficiency of the Boost Inverter than the SVPWM and PFADPWM methods.

Wide-band-gap devices such as SiC MOSFET and GaN devices have distinct advantages of high speed and lower switching loss. However, they have higher dv/dt and may cause larger EMI noise. In this paper, design of voltage slew rate on SiC MOSFET devices with soft-switching is investigated. The dv/dt of power devices in the three-phase active-clamped zero voltage switching (ZVS) inverter is analyzed. The voltage slew rate of power devices vs. resonant parameters is discussed. Then the design of dv/dt on power devices are proposed. The dv/dt design has been verified through both the simulation and the experiment on the 10 kW/100kHzSiC-based ZVS three phase inverter.

Model-based predictive current control (MBPCC) methods have been applied in the field of motor control due to its better dynamic response and intuitive design, but the high performance of MBPCC are easy to be influenced by parameter mismatch which could lead to the deterioration of control performance. In this work, a model-free predictive current control method based on ultra-local model with moving horizon estimator (MFPCC-MHE) is proposed to overcome the influence of parameter mismatch on the MBPCC to improve the robustness of system and simplify the design of current loop. The total disturbance of system which contained known terms and unknown disturbance terms are obtained by MHE accurately. Simulation results show that the proposed MFPCC-MHE realize the effectively eliminate the influence of PMLSM parameter mismatch and has good robustness.

Photovoltaic (PV) industry has been rapidly grown over the past decades. PV modules are the component of the PV systems that is easily susceptible to rigorous working conditions, which can result in a variety of defects affecting the system’s performance and lifespan if not diagnosed in time. Thus, it is necessary to understand the characterization of each fault and principles of every diagnosis method. This paper provides a comprehensive review of common faults within the context of the PV arrays, addressing the faults type, causes, and their effects on the I-V curve performance. In the previous studies, the main focus of overview is the efficiency and reliability of the direct diagnosis methods. As an important control method, the application of maximum power point tracking (MPPT) has become more and more extensive. This review also presents the latest MPPT-based techniques for diagnosing PV faults. Then techniques for PV diagnosing proposed in recent literature are analyzed and compared to point out their differences, the advantages and limitations and so on. This review will be of more interest to researchers and engineers working on PV power systems.
