Short Course: Circuit and Field Simulations in High Voltage Power Supply (HVPS) Practice
8:00am - 12:00pm
Location:Royston Room B3
For short courses in the Marriott
Presented By: Dr. Alex Pokryvailo
The course 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 course focuses on power circuitry of high-performance switchmode power supplies ranging from units to hundreds of kV and up to hundreds of kW although some examples expand to nanosecond pulsers. First, pertinent topologies of HV converters are reviewed. Necessary trade-offs combining high dielectric withstand with small dimensions and low and/or controlled parasitics are described. The target of the circuit simulations (PSpice platform is used) are dc-to-dc converters as the most challenging blocks of HVPS. The emphasize is on defining the parasitics from field simulations, ultimately, to the level of performing coupled analyses. Field simulations, see partial list of references, encompass electrostatics (for insulation design), electromagnetics (design of transformers, chokes, etc., with account for eddy currents), heat transfer and multiphysics. An example of the latter would be CFD problems related to electrohydrodynamics, e.g., oil driven by electrostatic forces.
