Circuit and Field Simulations in HVPS Practice

#high #voltage #pspice #field #simulation #converters

This lecture is intended for engineers and researchers in the field of high voltage electronics who want to
use circuit and field simulations in everyday practice of designing HV power supplies. Influenced heavily
by the instructor experience, the lecture focuses on the power circuitry of high-performance switch-mode
power supplies ranging from units to hundreds of kV and up to hundreds of kW. The target of circuit simulations made on a PSpice platform are dc-to-dc converters as the most challenging blocks of HVPS.
The emphasis is on defining the parasitics from field simulations, ultimately, to the level of performing
coupled analyses. Field simulations encompass electrostatics (for insulation design), electromagnetics
(design of transformers, chokes, etc., with account for eddy currents), heat transfer and multi-physics. An
example of the latter would be CFD problems related to electro-hydrodynamics, e.g., oil driven by
electrostatic forces. Most of the topics are illustrated by simulations of real-life systems

Circuit & Field Simulations in HV Power Supplies


Alex Pokryvailo (M’05–SM’07) was born in Vyborg, Russia. He received the M.Sc. and Ph.D. degrees in
electrical engineering from the Leningrad Polytechnic Institute in 1975 and 1987, respectively. Formerly
with Soreq NRC, Yavne, Israel, now he is with Spellman High Voltage Electronics, serving as Director of
Research. His current and recent experience relates to research and design of HV high-power switch-mode
power supplies, insulation testing, multi-physics simulations, pulsed power, fast diagnostics, and corona
discharges. Previously, he studied switching arcs, designed SF6-insulated switchgear, researched
interaction of flames with electromagnetic fields, etc. He has published 150 papers, two textbooks (in
Hebrew), and more than 20 patents pertaining to HV technology. He has also taught undergraduate and
graduate courses on HV techniques in Israel and USA
