Multi-level topologies reduce the requirements on inductors and filters, however, given the high number of series connected semiconductors, it is still unclear if they are a suitable option to achieve ultra-high efficiency while maintaining a reasonable power density. For this purpose, an extensive quantitative evaluation of different topologies is carried out, to determine the required volume for a targeted 99.5% efficiency of a 10kW three-phase inverter. This includes the EMI noise filtering, where the Common Mode filter is placed on the DC-side to save losses and the impact of the upcoming EMI regulations covering the range from 2 kHz to 150 kHz is discussed. With an evaluation of multilevel topologies, it is shown that even if a high number of levels can reduce the size of the magnetic components by an order of magnitude, the volume and losses of the capacitive components required to create the multi-level voltage output have to be considered. An evaluation is done to quantify the performance of topologies ranging from two-level to seven-level topologies, and detailed designs of the three-level T-type and seven-level Hybrid Active Neutral Point Clamped converters are presented, achieving a relatively high power density of 2.2 kW/dm3 and 2.7 kW/dm3 respectively.

The purpose of this paper is to improve dynamic characteristics of dc-dc converters in the information and telecommunications system by using a proportional and integral gain changeable control method. Generally, stability becomes worse and a limit cycle oscillation occurs when large PID control gains are used. In the proposed method, the proportional gain is risen during a transient state to improve the transient response and avoid the limit cycle oscillation. Also, the integral gain is set to a small value in the continuous conduction mode and a large value in the discontinuous conduction mode. As a result, the proposed method has a superior transient response and high stability to a conventional fixed gain PID control method.

A dual active bridge (DAB) converter is a widely used structure in the low voltage direct current (LVDC) distribution system. In the case of the conventional single-level DAB, the higher the input and output voltage, the higher the voltage stress that the power switch must withstand. To solve this problem, a multi-level structure can be applied to the DAB converter to have low voltage stress of the power switch. Among the multi-level structures, the neutral point clamped (NPC) type is the simplest and most effective in its structure. However, due to the use of two capacitors in series at the DC-link, a capacitor voltage imbalance occurs. If a capacitor voltage imbalance occurs, the voltage stress applied to the power switch can exceed the rated voltage. Conventional capacitor voltage balancing algorithm operates using PI controller. However, precise PI coefficient is required. Therefore, in this paper, a 3-level NPC based DAB converter is analyzed and a new capacitor voltage balancing algorithm without the PI controller is proposed. Finally, the above proposed algorithm is verified by the experimental results of a 1 kW prototype.

This paper faces the technical and economic challenges related to the design of a green recharge area for electric vehicles at the Campus of Palermo, Italy, with the aim of reduce both costs and pollution connected to the charging process. Based on the behaviour of the student population, the electrical load is identified and two possible solutions are evaluated to manage the peak load: an orientation of the panels increasing the power at defined time and the use of a storage system. The main strength and weakness points of two systems are investigated by taking into account the Levelized Cost of Energy (LCOE), which reaches 75.3 €/MWh for the orientation of panel and 103 €/MWh for storage system. Furthermore, the cost of the topologies of power plant and the cost of energy are deeply discussed.

Flyback converters are widely used in telecom applications with two of the most popular being in point-of-use power supplies and as part of two-stage AC-DC converters. They can be implemented with either passive snubbers or active snubbers for the main converter switch. Active snubbers are generally thought to be more efficient but more expensive than passive snubbers, but recent developments in passive snubber technology has resulted in increased efficiency. The performance of an example passive snubber is compared to that of the popular active clamp snubber in the paper. In the paper, the operation and features of the two converters is discussed, along with the design of the example passive snubber. The efficiency of the two converters is compared with results obtained from prototype converters and conclusions as to which converter is better are made.

Cell voltage equalizers are important for the batteries of electric vehicles and other energy storage systems in order not to be reduced their capacity. The authors have proposed a cell voltage equalizer using an LC series circuit; however, the equalizer requires a lot of bi-directional and multi-stage connected switching elements to equalize the voltage across each battery cell. This paper proposed a novel gate drive circuit configuration and a control method which has compatibly with high performance and low costs using “MOS-FETs” and verified the effectiveness of the proposed method by the simulations and experiments.

In direct current (DC) system, there is no zero-cross of voltage curve, so that dangerous arc discharge shall be occurred inevitably between poles. Also, inrush current must be occurred in capacitors inside of ICT equipment. These unpreferable phenomenons will be happened at every movement of connect and disconnect. So, stable protection shall be necessary for human safety. New appliance coupler with safety functions to avoid damages of both inrush current and arc discharge has been developed and this paper explains its developed mechanism and reports the significant result of verification tests. There has never been industrial standard for appliance coupler of LVDC yet. Even in IEC, this is still on discussions. So, verification tests in this paper were performed compliant to IEC TS 62735-2 which was already published and specifies Plug and Socket-outlet of 400 Vdc for data centers.

The active power filter (APF) has already established itself as a prominent means of addressing harmonic pollution and other power quality issues. Current control of an APF is a key in achieving a good compensation performance. Generally, PI control is used owing to its simplicity and ease of implementation. However, using a proportional resonant (PR) controller can give an added advantage in tracking of harmonics at higher frequencies. This paper presents a comparative study of current control when implemented using PI and PR controllers in a platform of a three-phase three-level shunt APF. The simulation results prove the effectiveness of PR control over PI control.

The future electricity grid for the electric power distribution network is slowly moving in the direction of dc transmission. In order to prevent the fault propagation, provide protection against overload and fault, and isolate the faulty load in a dc power network, an overcurrent protection device must be applied to the switch gear for electric power management and control of the systems in dc power network. Overcurrent protection devises such as electromechanical circuit breaker in the primary and secondary distribution systems will protect all branch circuits on the load side of the discharge bus. This type of circuit breaker has the conflicting of time delay characteristics that trip delays must be long enough to open the circuit when a real fault exists. It should cause nuisance tripping. We are developing a solid state type of power switching circuit for dc power network instead of electromechanical circuit breaker. The candidate for these switching devices should be Power MOSFET, IGBT, and SiC MOSFET. Focusing on the application for the low and medium voltage dc grid, fast-acting switching function and current limiting features are brought up the idea to apply Si Power MOSFET, IGBT, and SiC MOSFET to the dc circuit breaker. The very basic evaluation for this fast-acting switching and current limiting function for the dc circuit breaker are shown by experiment in this paper. Our prototype switching device will open within 20 μs and we can freely adjust this elapsed time and fault current rating. To avoid nuisance tripping, we successfully performed current limiting function by extend the elapsed time using same control circuit.

Recently, energy policies have been adopted by various countries around the world to realize a low oxygen society. Attention has been paid to self-sufficient smart home technologies to reduce energy consumption. Power storage devices integrated into photovoltaic power generation devices have been introduced in smart homes. Such power storage devices are mainly used to decrease power peaks and shift peak loads in addition to providing emergency power supply. However, how to discharge the power storage device is not considered much. Furthermore, it has been reported that the service life of power storage devices depends on their operation method. In this study, we propose a control method of power storage system used for grid system for distributed power supply and investigated the characteristics of power storage device in each control method. The experimental results show that the tested discharge control method is operated without putting a heavy burden on the electricity storage device.
