More Information

The picture consists of 4 single pictures. At the top a current of a DC/DC application is shown, at the second place a corresponding component with oscillations around it and at the third and last place a diagram of the current flow is shown.

Losses in storage chokes are one of the crucial factors in the design of efficient power supplies. With our world's most accurate AC loss model in REDEXPERT, the complete AC losses can be precisely simulated at any operating condition.

Advantages of the Würth Elektronik AC Loss Model

Components
  • All core material types
  • All core geometries (not only toroidal cores)
  • Air gap and associated fringing effects
  • Effects and changes in winding structure
  • DC bias is taken in consideration for inductor recommendation and calculations
Method

The model was measured with a square wave voltage resulting and a triangular inductor current.

Accuracy

Compared to Steinmetz, the Würth Elektronik model provides higher accuracy over a wide range of duty cycle.

With this application, you can design a discrete EMI filter for conducted differential noise from your input parameters. This application takes the guesswork out of EMI and reduces the time and cost.  It is the first filter tool from a component manufacturer on the market.

Functions

  • Topology recommendation based on impedance, insertion loss & cutoff frequency
  • Component recommendation considering noise source and load impedance, cutoff frequency and parameters
  • Automatic selection from thousands of components
  • Shows insertion loss and input/output impedance
  • Simulation of non-ideal components
