Auto Design 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.

  • Voltage waveform input
    • Sinusoidal
    • Square
  • Converter input
    • Boost
    • Buck
    • Buck-boost
    • Forward
    • Half-bridge
    • Full-bridge
    • Push-pull
    • Flyback converters
The PExprt template-based interface enables easy input of voltage waveform or converter input to start the design process.

Models Models

  • PExprt generates accurate models for use in ANSYS Simplorer 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, end effect
      • Valid for arbitrary winding strategies
      • Intra-winding interleaving, twisted wires
      • Bi-filar or tri-filar wires
      • Parallel connections
ANSYS PExprt models can be used in ANSYS Simplorer to study the effect of the magnetic component on the circuit.
