ANSYS PExprt Features
Auto Design
ANSYS PExprt can automatically create a design from voltage waveform or converter inputs. The auto design process considers all combinations of core shapes, size, material, gap, wire type and gauge, and winding strategies to optimize the magnetic design.

- Core shapes: POT, RM, EE, EI, EFD, ETD, UU, EP, PQ, toroidal, T, I, DRUM, UI, laminated
- Conductors: Litz, solid, planar tracks, planar technologies, twisted, square and foil
Modeling Capabilities
PExprt generates accurate models for use in ANSYS Twin Builder or other circuit simulators, easing the burden of creating a prototype and measuring the magnetic component. Models account for:
- Winding position and stacking, including interleaving
- Intra-winding capacitance
- Temperature
- Skin and proximity effects
- Material characteristics, including nonlinear and hysteresis behavior of the core
- Frequency-dependent resistance, leakage inductance and magnetizing inductance
- Gap effect and end effect
- Valid for arbitrary winding strategies
- Intra-winding interleaving, twisted wires
- Bi-filar or tri-filar wires
- Parallel connections
