PSIM Expert – Design of Power Factor Correction (PFC) converters
 Place: Stuttgart, Germany Date: September 24 – 25, 2019
 Course fees: 990 Euros* for industrial participants.
750 Euros* for academic participants.

* Instructors: – Dr. Antonio Lazaro Blanco
 Language: English
 Public and technical background required
The training course is recommended to everybody interested in the theoretical aspects and practical design issues of digital control of voltage source converters. Having previous experience in power electronics and circuit simulation is useful, but beginners with no background in those topics will also benefit from the course.
 Training Objectives The objective of the course is to acquire the fundamental competences in single-phase and three-phase PFC converters. These competences are:

 Selection of the best topology for each type of application (EV chargers, motor drives, aerospace AC/DC front-end converters and power supplies). Inductors design under the specific requirements of the PFC operation. Effective Cots inductor selection. EMI filter design. Power losses calculations and MOSFET / IGBT / Diodes selection. Dynamic analysis of dynamic modeling of PFC converters. Simple but deep understanding the PFC control loops. Effective analog and digital controller design using SmartCtrl. Effective PSIM simulation of 1-ph & 3-Ph PFC converters (including conducted EMI estimation by simulation). In addition to the topology selection, specific aspects regarding the previous competences will be shown for each type of application. Antonio Lázaro was born in Madrid, Spain, in 1968. He received the M. Sc. in electrical engineering from the Universidad Politécnica de Madrid, Spain, in 1995. He received the Ph. D. in Electrical Engineering from the Universidad Carlos III de Madrid in 2003. He has been an Assistant Professor of the Universidad Carlos III de Madrid since 1995. He has been involved in power electronics since 1994, participating in more than 50 research and development projects for industry. He holds seven patents and software registrations and he has published nearly 140 papers in IEEE journals & conferences. His research interests are switched-mode power supplies, power factor correction circuits, inverters (railway and grid connected applications), modeling and control of switching converters and digital control techniques.

Operation and Control Strategy of a New Hybrid ESS-UPS with Function of Demand Management and Emergency Power Supply- Kim, Sang Jin-The Graduate School of Industry and Engineering Seoul National University of Science and Technology

Operation and Control Strategy of a New Hybrid ESS-UPS with Function of Demand Management and Emergency Power Supply Kim, Sang jin (Supervisor Choi, Se Wan) Dept. of Electrical and Instrumentation Eng. The Graduate School of Industry and Engineering Seoul National University of Science and Technology

This paper proposes a hybrid energy storage system (ESS) that integrates an ESS with an on-line uninterruptible power supply (UPS). The power conversion system (PCS) cost of the proposed hybrid ESS-UPS is reduced, and battery utilization is increased by using the energy of the integrated battery for both demand management and emergency power supply. Further, unlike the conventional on-line UPS, the proposed hybrid ESS-UPS is capable of supplying emergency power to two types of critical loads, voltage-frequency independent (VFI) load and voltage-frequency dependent (VFD) load. A seamless mode transfer algorithm of the ac-dc converter is proposed for supplying uninterruptible power to the VFD load as well. In addition, an autonomous and seamless mode transfer algorithm of the bidirectional dc-dc converter is proposed to minimize the transient across the dc-link that could affect the power quality of the VFD load and the VFI load at the mode transition. To validate the proposed control scheme, experimental results from a 5 kW prototype are provided.

Abstract
With the active technological development of modern communication systems, advanced medical equipment, advanced living facilities, and emergency systems that requires high-quality energy are more and more widespread used in everyday life, which require more reliable, efficient, and uninterrupted electricity supply. Due to increase of these critical loads, a power supply with high quality and reliability is more important than ever. Consequently, Uninterruptible Power Supply(UPS) has recently experienced a growing demand. According to the International Electrotechnical Commission Standard IEC 62040-3, the UPS systems are categorized into on-line UPS, off-line UPS, line interactive UPS according to the energy flow direction under normal utility condition. Among them, The on-line UPS is receiving more intention from the researchers and engineers because of its outstanding capability of suppressing grid frequency variation, voltage irregularity and other power issues. However, because the stored energy of UPS battery is used only when these issues happen, battery utilization rate is very low. Therefore, hybrid UPS that integrates ESS with an on-line UPS has recently developed. Unlike the conventional UPS, hybrid UPS can increase battery utilization rate by using the stored energy of battery when the grid is under normal operation. whereas when the grid fails, hybrid UPS has to supplies emergency power to critical loads. Therefore, transient voltage across the DC-link that could affect the power quality of critical loads can occur during mode transition. this paper addresses new operation strategy of three phase hybrid UPS with Energy Storage System(ESS) function to minimize the transient voltage across the DC-link. PSCAD/EMTDC software is used to verify validity of the proposed operation scheme.
