  • Variable frequency (10kHz-1MHz) and duty cycle (5...95%)
  • DC bias voltage up to 70V
  • Ambient temperature control : -60 ... +225°C
  • AC-loss measurement
  • Self-heating measurement
  • Understanding losses in power capacitors
  • Separation of dielectric losses
  • ESR and ESL measurements
  • Safe-operating area determination under real-life operation
  • SPICE Model extraction
  • Non-linear effects investigation
  • Development of capacitors
