Inductance measurement using the Power Choke Tester DPG series

For all inductive power components

Power Choke Tester DPG Series

Power Choke Tester DPG Series


The large-signal impulse measuring method provides a complete inductance curve as a function of the current L(i) or as a function of the applied time-voltage-integral L(∫Udt). Thus the saturation characteristics of the power inductor can be seen clearly at a glance.

Besides the incremental inductance and the secant inductance a lot of other variables can be measured.

Meanwhile our Power Choke Tester DPG10 series is established worldwide as a standard measurement instrument in development, production and quality control of inductive power components.

Specifications


  • Measurement of the incremental inductance Linc(i) and the secant inductance Lsec(i)
  • Measurement of the flux linkage ψ(i) and the magnetic co-energy Wco(i)
  • Measurement of the DC resistance
  • Calculation of the flux densitiy B(i)
  • By means of the optional 3-Phase Extension Unit also suitable for 3-phase chokes
  • More realistic measurement results compared to small signal measurement with DC bias or 50/60 Hz mains current measurement

Applications of  inductance measurement


  • Development, research and quality inspection
  • Routine tests of small batch series and mass production
  • Very wide current range from <0.1 A up to 10000 A => suitable for all inductive components from small SMD inductors to very large power reactors in the MVA range, e.g.
    • Filter inductors for switch mode power supplies, DC/DC converters etc.
    • Filter inductors for uninterruptible power supplies, inverters etc.
    • Power chokes for PFC etc. and commutation inductors
    • Suppression chokes and Current compensated chokes
    • Solenoids, coils of valves
    • Transformers for flyback converters
    • Power transformers, motors
    • and much, much more inductive components
