Recent Advances in the Field of Electric Power Quality

Abstract — The field of Electric Power Quality (PQ) is gaining the interest of many researchers from academia and industry. The main reasons behind this are the increased complexity of the power system, widespread usage of non-linear power converters, the addition of renewable energy sources and distributed generation, rise in electric vehicles and other means of electric transportation with high charging demand, and electrical storage capacities, etc. On the other hand, the digitalization of the power system is increasing and applied advanced computer systems, microprocessor-based devices, and digital control systems are very sensitive to PQ disturbances. There are different types of PQ disturbances, but voltage distortions and disturbances, like harmonics, sags/swells, flicker, interruptions, etc., are the most interesting ones. Each type of PQ disturbance is characterized by a specific signal signature (feature), which needs to be adequately detected, classified, characterized, and recognized as a possible threat (or not) to normal operation. Modern methods of the PQ signals treatment are based on traditional Nyquist methods and different analysis approaches are available. Usually, the voltage is defined by tracking its r.m.s. value with different methods of its calculation. But, digital signatures of the PQ disturbances may be analyzed with advanced digital signal processing methods, like parametric, nonparametric, and hybrid ones. Recently, compressive sensing methods have been introduced for signal digital treatment and transmission, while for the disturbances classification, characterization, and possible localization artificial intelligence, through machine learning was applied.

The lecture is intended to present an overview of different PQ signals analysis methods and their application in the characterization of PQ events. Special focus will be given to harmonics, as they may be a source of possible resonance in the network, and advanced voltage sags/swells detection and characterization methods, as they may have serious implications on power electronics converters operations, i.e., on RES generation, industrial drives and other loads operation and reliability. The methods using harmonic footprint and deep-learning algorithms will be presented in more detail.

Integrated Circuit Reliability: Current State, Challenges and Solutions

Abstract — At present integrated circuit (IC) development is related to a number of challenges, including power consumption, performance, etc. The most important one among them is IC reliability. The fact of becoming vital is conditioned by a number of famous physical phenomena, becoming crucial. Such phenomena are aging, signal integrity, power integrity, self-heating, protection from electrostatic discharge and latchup, radiation effects, process variability, metastability, etc. The mentioned phenomena have always had impact on IC functioning and its main parameters. However, due to IC scaling, their role has become crucial. As a result of IC scaling on one hand, the impact of the mentioned phenomena on ICs has constantly increased. On the other hand, during time IC is becoming more sensitive towards those impacts. All this creates huge difficulties during IC design. The lecture is intended to present what challenges each mentioned phenomena creates for an IC designer, what is the real situation now WRT each phenomena and what solutions are there that will allow to reduce the impact of those phenomena to an extent that IC reliability is at a necessary level.

Wireless Inductive-Charging of Electric-Vehicles is Coming

Abstract — The increased popularity of battery electric-vehicles (BEV) in recent years moved focus of the research and development activities towards future technologies for the charging-infrastructure. The wireless inductive-charging of BEV’s batteries is convenient, robust, efficient, and a reliable emerging charging-method.

The lecture will start with a short introduction of Brusa Elektronik AG—a pioneer in emobility. Brusa is the first company worldwide which launched an inductive-charging system (ICS) for BEV certified per IEC 61980 in 2018 together with BMW. Current status of the charging infrastructure, future system needs, and trends will be briefly covered. One will see that the wish for wireless ICS actually comes from the BEV drivers who are fed-up with handling of the charging cables. The ICS fulfills the need for automated charging-systems and is prepared for future applications like semidynamic charging.

After that performance of Brusa 2nd generation ICS (11 kW) and comparison to the 1st generation (3.6 kW) ICS will be addressed. Both the vehicle and the infrastructure units will be covered. Besides power electronics, the ancillary functions such as foreignobject detection (FOD), living-object protection (LOP), and positioning (POS) will be briefly discussed.

The lecture will be closed will overview of upcoming ICS improvements and challenges including efforts in standardization. At the end short video will be played showing how automatic wireless inductive-charging works in reality thus demonstrating its performance and potential.
