MADMIX

Power Inductor Measurement

The MADMIX inductor measurement system is the standard for measuring power inductors AC-losses under real-life, large-signal triangular flux excitation conditions.

Key Features

Hard-switched voltage, triangular current excitation
Variable frequency (10kHz-10MHz), voltage (0.5-70V), DC-bias (0-48A), duty-cycle (5-95%) and temperature (-60- +225°C)
AC-loss, core/winding-loss measurement
Self-heating measurement
Coupled-inductor measurement

Benefits

Understanding losses in power inductors
Safe-operating area determination under real-life operation
SPICE Model extraction
Non-linear effects investigation such as saturation

Applications
