The input current harmonics of battery chargers affect harmfully on the overall power distribution network. They result in voltage distortion, heating transformers, reducing conduction capacity of cable, and affecting the interrupting capability of circuit breakers. In order to eliminate these problems, this paper presents an effective control scheme to remove input current harmonics of battery charger by controlling the current in phase with fundamental component of the grid voltage. The proposed control scheme not only achieves near-unity input power factor but also eliminates current harmonics in the battery charger regardless of the grid voltage disturbance. To validate performance of the proposed control scheme, both simulation and experiment are carried out.

In the large system such DC distribution for building, the method that a number of modules converters operation in parallel is commonly used. When parallel operation, circulating current is directly related to the loss of the entire system. Accordingly, each module to share the same current is the most important for the safety of the power system. In this paper, control method for reduction circulating current in parallel operation is proposed. Thus, Response and operation of steady-state with parallel system was verified by simulation and experiment.

This paper deals with the ellipse permanent magnet machines for the minimization of torque ripple based on electromagnetic field theory. On the basis of a magnetic vector potential and a two dimensional (2-D) polar system, analytical solutions for flux density due to permanent magnet (PM) and current are obtained. In particular, the analytical solutions for mathematical expressions of magnets with different circumferential thicknesses can be solved introducing improved magnetization modeling techniques. The analytical results are validated extensively be nonlinear finite element solutions, a reduction of torque ripple can be achieved.

The paper presents experimental results from the operation of a proto-type green ship in Geoje island, South Korea. After ground testing with a stand-alone PV generation system, this PV system was added to conventional diesel ship. Proto-type green ship is consisted of photovoltaic (PV) generation system, diesel engine, battery energy storage, hybrid control system, stand-alone and grid-connected inverter. The aim of the green ship is not only to minimize the fuel consumption but also to support the power grid as a distributed generation (DG) in the near future.

A novel electrified bicycle using only ultracapacitors as the primary energy storage components are described. A specific buck converter to charge the e-bike in less than two minutes has been designed and simulated. The simulation of the associated fast-charging system shows that this technology is feasible for the intended application. Novel ultracapacitors, made from Carbon Nano-Onion materials, have been produced and the impedance spectra were measured. The data were fitted to an equivalent electrical model and the parameters for the ultracapacitors were determined. It is possible to increase the total viable e-bike distance by 22% by using nanocarbon materials, such as nano-onions, for energy storage.

With battery emulators, development engineers can test electrical drives on testbeds without the need for costly battery prototypes. Furthermore, valuable time for battery pre-conditioning can be saved. However, high quality battery emulation is a challenge that requires a good battery model and accurate emulation of the model with a controllable power supply. A high-fidelity nonlinear battery model based on local model networks is used. This allows the extraction of local linear models for impedance emulation with a switch model DC-DC converter. Local linear battery models and a model of the converter are combined to a prediction model which is used for designing a model predictive controller. In contrast to existing impedance emulation schemes with cascaded feedback loops, the virtual impedance is included in the inner voltage control loop in order to achieve the highest possible bandwidth. Owing to constrained optimal control, this is achieved while respecting control variable constraints and inductor current safety limits. Experimental results show the effectiveness of the proposed battery impedance emulation scheme.
