Circuit and Field Simulations in HVPS Practice

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.
