ANSYS PExprt

ANSYS PExprt is a specialized software program for the design, analysis and optimization of transformers and inductors found in power electronic applications. Using a combination of classical and finite element analysis (FEA) techniques, PExprt determines the appropriate core size and shape, air gaps, and winding strategy of the component for optimum reliability and performance or other user-specified criterion. PExprt provides unique insight into design issues such as gap energy, current density in windings, leakage flux (leakage inductance) winding capacitance, proximity and skin effects, interleaving and integrated windings. This tool also allows detailed models to be created for ANSYS Simplorer to simulate the magnetic in the actual design to evaluate performance as well as power efficiency.

PExprt is ideal for the design, analysis and optimization of transformers and inductors found in power electronic applications.

PExprt is ideal for designers of automotive and aerospace converters, switch mode power supplies and electronic ballasts. With PExprt, designers can quickly calculate all possible combinations of core size, core material, wire gauge, turns and gap length that satisfy user-supplied electrical specifications. The resulting "virtual" designs are then further refined and optimized using embedded finite element calculations to predict quantities such as magnetizing and leakage inductance, interwinding capacitance, peak flux density, DC winding resistance, eddy current effects and core loss. PExprt also generates an equivalent circuit model accounting for magnetic and thermal properties for use in Simplorer for complete circuit optimization.
