Modeling, Simulation, and Experimental Investigation of High-Frequency Effects in Power Electronic Based Systems 981268

High-frequency problems in power electronic based systems have become of greater concern due to increases in device switching speed, and faster edge rates. Fast device edge rates excite parasitics throughout the system. It is essential for designers to be able to anticipate undesirable electromagnetic compatibility problems that arise as technology continually advances. In this paper the aspects of high-frequency modeling of a 3-phase 5 hp induction motor, a 3-phase 3/4 hp surface-mounted permanent-magnet synchronous machine and drive system (brushless DC machine), and a discrete insulated gate bipolar transistor (IGBT) will be discussed. Computer simulations agree well with measurements.
