Mr AMIT PATEL (ITER-India , Institute for Plasma Research)07/07/2016, 10:00Power Electronics and High VoltageOral PresentationHigh Voltage Power Supply (HVPS) based on PSM (Pulse Step Modulation) topology has already demonstrated its ability for broadcast transmitters, accelerators of RF source, neutral beam injectors. Typical IC RF system composed of cascaded connection of Driver stage and End stage would need two power supplies. A novel concept of tapping two outputs from single PSM based HVPS is attempted for the...Go to contribution page

Sebastian Blume (ETH Zürich)07/07/2016, 10:15Power Electronics and High VoltageOral PresentationA new type of particle collider in the tera-electron-volt (TeV) energy range, the Compact Linear Collider (CLIC), is currently investigated at CERN [1]. In CLIC each klystron is supplied by a separate pulse modulator, which is able to provide 29 MW of pulse energy at a repetition rate of 50 Hz. This energy corresponds to an average continuous power of 210 kW. The 180 kV pulse is generated by a...Go to contribution page

Alexander Pokryvailo (Spellman High Voltage Electronics Corp.)07/07/2016, 10:30Power Electronics and High VoltageOral PresentationEnergy-dosing (ED) topology was shown to be effective for capacitor charging and long- flat-top pulse generation (see [1], [2] and their bibliography for examples of implementation and for the theory of operation). The inherent advantages for these applications are zero-current switching and excellent predictability following from the ED principle of operation. As the term ED implies, the...Go to contribution page

07/07/2016, 10:45Power Electronics and High VoltageOral PresentationThe measurement of partial discharges is sustained in the detection and filtration of current pulses which appear in a band of frequency that include from the kilohertz up to the gigahertz, for such a reason the partial discharges detectors possess systems for the separation of this current pulses. However, partial discharges detectors also allows the pass of other signals of high frequency,...Go to contribution page

Mr Jinyu Li (Xi'an Jiaotong University)07/07/2016, 11:00Power Electronics and High VoltageOral PresentationIn a HVDC converter station, filter capacitors，specifically the can-type capacitors, are the main noise sources after transformers and reactors. It is necessary to investigate the filter capacitor vibration and noise reduction measure. Capacitor current contains fundamental and high frequency harmonics, which cause high-frequency alternating forces on the internal capacitor element, lead to...Go to contribution page

Andras Kuthi (University of Southern California)07/07/2016, 11:15Power Electronics and High VoltageOral PresentationA high power, high repetition rate, fast capacitor charging circuit is presented. The circuit uses four SiC MOSFET switches in parallel in a modified boost converter configuration. Switching losses, already reduced due to the fast switching characteristics of the SiC devices are further mitigated by an auxiliary switch enforcing zero voltage turn-on of the main switches. The charging circuit...Go to contribution page

07/07/2016, 11:45Plasmas, Discharges, and Electromagnetic PhenomenaOral PresentationLightning is one of the major natural disasters threatening aircraft flight safety. Aircraft lightning zoning is the premise of lightning protection design, and the first step in locating the lightning striking zones is determining the locations where lightning leaders may initially attach to aircraft. The lightning strike to aircraft starts with the development of a positive discharge from...Go to contribution page
