Electrical Machines, Solenoids and Sensors - The Art of Electromechanical Component and System Design
The key to electromechanical component design is to analyze as many different configurations as possible in order to determine the design that meets its specifications at the lowest cost. Using parametrics and optimization, this paper discusses different numerical method techniques to solve this problem. Once this work is complete, the engineer needs to be confident that this component will work properly in the system for which it was designed; thus the ability to create an accurate model of the component to be used in a system level simulation is essential. This paper will discuss component modeling methods and its use in system simulation.

Power Factor Correction Design with Simplorer® and PExprt™
This presentation describes a procedure to analyze the Power Factor Correct (PFC) circuit and design the PFC inductor by combining Simplorer® and PExprt™. Simplorer is used to simulate the Power Factor Correct (PFC) circuit. The user can study the PFC performance and change the corresponding components to satisfy all the specifications. Meanwhile, the user can obtain all the inductor design parameters required for PExprt from the Simplorer simulation. Then the designer can input the inductor parameters into the PExprt interface. The available designs are list graphically and can be sorted by size, temperature rise, or height for the designer to choose from.
