PExprt Static Coupling Components

PExprt Static SML coupling components derive from analytical models of magnetic components such as inductors and transformers. 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 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, core loss, and temperature rise. PExprt generates an equivalent-circuit model (SML) accounting for magnetic and thermal properties for use in Twin Builder for complete circuit optimization.
