The objective of the discrete-time modeling tools is twofold. First, they give an insight into the basic ideas of discrete-time modeling of dc-dc converters for university students and interested power electronics specialists. Second, as it is being presented below, the interactive calculation tools facilitate the fast and simple model development in WEB browser after entering the basic circuit and...
Calculation technique to obtain radiated electric far-field from assembled device: chassis with PCB has been investigated. Circuit model including ground and power planes are created in PSPICE in order to calculate frequency spectrum of the current flowing through the screw at different location. Next, simplified 3D chassis model are created with simplified PCB model which does not have any traces...
Resolver is widely used in electric drive system especially for hybrid electric vehicles (HEV). A resolver system includes not only a variable-reluctance resolver but also an excitation circuit, shielding cables and a resolver-to-digital (R/D) IC as a multi-physics system with electrical, magnetic, mechanical and control characteristics. This paper studies a resolver for HEV electric motor, and proposes...
This article presents the power point presentation on the overview of component level testing for HEV products and simulating actual vehicle condition at component-level that would be the most important. A fundamental study of the emission from HV system was calculated and characterized with consideration of effects from HV related typical parameters. The noise source and effects of low voltage system...
The main objective of the paper is to present new browser-based, interactive software tools for modeling of various power electronics circuits. The static and dynamic operation, including the continuous and discrete time linearization of widely applied DC-DC converter cells are discussed in the first part of the paper. The second part focuses on the basics of the pulse-width-modulation and its application...
