Inductance measurement using the Power Choke Tester DPG series
For all inductive power components
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
