The DC-DC converters at the Advanced Photo Source at Argonne National Laboratory are over 15 years old. An upgrade to digital control system is being evaluated to resolve the aging and obsolescence issues. These converters supply power to electromagnets that are used to guide high energy beams. Thus a highly accurate control system is required for the DC-DC converters. This paper describes the design and evaluation of a digital control system to regulate the output current. The digital control system is proposed to replace the current analog control system thereby resolving the aging and obsolescence issues. A digital controller is first designed based on the small signal model of the converter. Experimental data of the output current is analyzed. The complete control system is then simulated and results are evaluated.

This paper presents a multifunctional bidirectional converter. The proposed converter works as a grid-tied inverter, injecting power coming from a PV subsystem to the AC mains in the daytime hours, but also supplies energy to a LED-based street lighting system at night. The topology is based on the integration of two Flyback converters thus allowing the desired bidirectional energy flux. Each Flyback has a different polarity, making energy flowing in both directions possible. A prototype was built in order to prove the feasibility of the proposed topology and experimental results are shown below. In rectifier mode, an efficiency of 86% was achieved while a 88.9% in inverter mode.

This paper presents a solution to energy quality problems in an open pit mine distribution system. Specifically, mine shovel operation is frequently disrupted by energy quality issues. A number of alternative approaches to deal with this problem include: the use of reactive power compensator technologies (i.e. passive filters; electronically switched capacitor banks and static VAR compensators), imposing limits to mining cable lengths, increasing cross sections of the surface cables and increasing the power of mobile substations. However, for this industrial site those alternatives fail to obtain the desired power quality and are not compatible with a potential expansion of the mine pit. This paper presents a solution based on IEEE recommended practices by adding a new feeder with higher rated voltage to the mine loop. The result is better shovel availability, a reduction in arc flash risk and a 9.55% improvement in energy efficiency. There is also a carbon footprint reduction of 10.7 kTon of CO2 per year.

This paper presents the design and development of an electronic ballast for electrodeless fluorescent lamps operating at 250 kHz. In this system, a dimming control based on a low-frequency modulated PWM signal is proposed. The topology is composed of a Single-Ended Primary-Inductance Converter (SEPIC), used as power factor correction stage, integrated with a resonant half-bridge inverter, used as the lamp power control stage. The integration of both stages is proposed in this paper, in order to reduce the number of active switches, as well as to simplify the required driving and control circuit for this application. Experimental results demonstrate the feasibility of the proposed solution that achieves 74% lamp power dimming (from 100 W down to 26 W). The implemented topology achieved a high power factor (0.99) with efficiency around 86%.

The demand for high speed electrical machines has increased recently, mainly in the electric or hybrid vehicles applications. Speeds as high as 13.000 rpm may be required, demanding new grades of electrical steels with improved magnetic properties. Such magnetic properties are typically characterized using parameters such as B50 and W10/400. However, improvements in these parameters do not necessarily translate into improvements of practical significance. This paper focuses on the performance improvements from newly developed electrical steels for high speed motors. Prototype motors were built for practical validation of the performance of these steels. Practical tests and finite element analysis are used to support the conclusions of this research work.

As plug-in electric vehicles (PEVs) are expanding, there is a growing need for widely distributed publicly accessible charging stations that supply electric energy for the recharging of the PEVs. In the charging station design, the proper distribution transformers that delivery reliable power from utility to the station are essential and important. To ensure economic and reliable operation of the charging station, the paper proposes a methodology for the PEVs charging station transformer design. A set of dynamic thermal energy models that describe the relationship between the transformer winding temperature and charging station load profile is derived according to ANSI/IEEE standards. The base load, PEVs demand, power quality, ambient temperature, transformer rating and connection all are taken into account. The models are then used to analyze PEVs charging impact on transformer loss-of-life and determine the proper transformer capacity and connection. The proposed method provides a better knowledge of the transformer effects and can be used for evaluating the level of PEVs that might be accepted on a distribution transformer. The models developed can also be used for determining proper transformers in the design of charging station distribution systems. The field testing results of a practical charging station for PEVs pilot projects in Taiwan confirm the validity of the proposed method.

Speed sensorless vector controlled induction motor drives have become very popular for motion-control applications due to their robustness. The performance of flux and speed observer is strongly influenced by the deadtime and inverter non-linear error at the low speed range. In most applications, the effect of deadtime can be offset by compensating the pulsewidth of PWM signal. However, the inverter non-linear error, such as voltage drop in switching devices, is difficult to compensate when the reconstructed phase voltage is utilized as the input of the observer, because it is not a fixed value. To solve the problem, in this paper the effect of non-linear error upon stator current estimation error is analyzed. A novel compensation method of non-linear error through the stator current estimation error is proposed. The proposed method separated the compensation of non-linear error from the deadtime compensation. Furthermore the nonlinear error can be identified directly off-line by the self-tuning method at the drive start-up and stored in the look-up-table. The experimental results demonstrate the feasibility of proposed method especially in the low speed range.

In case that the vibrating capacitive probe of an electrostatic voltmeter is facing a metallic plate of known electric potential V, which can be easily imposed by connecting it to a DC high-voltage supply, the value displayed by the instrument is equal to V. The same surface potential measurement technique is employed to characterize the charging state of insulating materials, such as films or non-woven media. The aim of the paper is to give some elements of answer to the following question: What significance can be attributed to the value displayed by the electrostatic voltmeter when the charge is non-uniformly distributed at the surface of the bodies examined by the probe and no constant surface potential can be defined? The measurements were performed for some simple experimental models that simulate surface potential non-uniformity. Thus, a copper wire, a copper rod, and two aluminium strips, connected to a high-voltage supply (V = 875 V) were located at 5 mm above a grounded metal plate. The vibrating capacitive probe was placed at various distances h above the grounded plate and at various distances x from the axial plan of the high-voltage strip/rod/wire - grounded plate system. Different V(x) curves obtained for each of the situations under study, pointing out that the value displayed by the instrument depends on the distribution of the potential across the surface examined by the probe. A commercial computer program based on the superficial charge simulation method was employed for the numerical analysis of the electric field in a simplified model of the geometric system formed by the probe, the high-voltage strip/rod/wire, and the grounded plate. The potential that anneals the electric field at the surface of the probe (to simulate its principle of operation) was calculated by an iterative method. A good agreement was found between the results of the numerical simulations and the experimental data.

This paper presents an energy quality evaluation of an open pit mine distribution system. A number of operational disruptions affecting mine shovels have been related to energy quality. Previous investigations have highlighted the large presence of harmonics as the main factor responsible for these problems. The aim of this paper is to produce an energy quality baseline and a precise diagnosis of the source and nature of the energy quality issues based on standards and the susceptibility of different technologies used by the shovels at the site. The random nature of the load composed by multiple shovels and drills requires computer simulation to predict worst-case scenarios. For this purpose a voltage regulation and harmonic distortion study was conducted with the model parameters tuned by measurements taken in mobile substations of the mine energy loop. A major aim of this study is to establish the relationship between energy quality and energy efficiency.
