Computer-aided optimization of DC/DC converters for automotive applications

Abstract

This paper investigates computer-aided optimization of dc/dc converters, with a focus on converters for dual-voltage automotive electrical systems. A new CAD optimization approach based on Monte Carlo search methods is introduced which allows the design space to be rapidly explored in an automated fashion and the most optimal designs and design approaches to be identified. The optimization approach also allows the effects of variations in design specifications on the cost, weight, and volume of an optimized converter to be readily determined. A prototype converter designed using this optimization procedure is evaluated and compared to a converter designed by conventional means.

IT Systems in Aid of Welding Processes Quality Management in the Automotive Industry

“…Such a facility will enable optimization of production costs. another task of the caD software is the transformation from geometrical model to the discrete one, properly prepared for later analysis using finite element method (FeM) [4,5,11].…”

“…each welding device is subjected to testing in virtual reality in order to verify the occurrence of errors or collisions. In the case of capture an error, the design changes in a virtual environment, which significantly reduces the cost of repair [4,5,11].…”

Two-Stage Optimization Method for Efficient Power Converter Design Including Light Load Operation

“…The design results have a lower implementation cost when compared with conventional designs satisfying the same specifications. Buck converter transient optimization design has been presented [8], also using GA. A Monte Carlo search method was developed to optimize the volume of an interleave converter for automobile applications [9]. The interleaved converters have more design variables than a single converter, and the optimization improvement of results seem more significant than a single converter optimization.…”

“…We can then obtain simple yet effective switching loss estimates. The turn-off energy consumed by primary MOSFETs is given by (9) with parameters summarized in TABLE II; we fixed the input voltage at 370 V in SPICE simulation.…”
