Core loss measurement
|High-frequency transformers used in switching power supplies and DC-DC converters suffer current leakage, which increases as the handled frequency increases. The causes of the leakage include hysteresis loss and eddy-current loss. The heat generated by lost current causes the temperature of the equipment to rise, making it difficult to reduce the size of equipment. Measuring core loss of soft magnetic parts provides the best solution to minimizing loss and enabling further reductions in equipment size.|
B-H curve measurement
|Magnetic saturation will be one of very important parameters to evaluate magnetic materials. The magnetic saturation can be determined by measuring the B-H curve.
In case a magnetic component is saturated in the condition you want to use it, it is difficult to expect inherent performance of it.
B-H Analyzer is the only instrument that can perform high accuracy B-H curve measurement of soft magnetic materials under various conditions in a wide range, from low-frequency to high-frequency of MHz bandwidth.
|Yoke materials used in motors, actuators and relays
are usually made of silicon steel, soft iron, permalloy and stainless
steel. However, these materials tend to cause differences in magnetic
characteristics according to the processing and heat treatment.
The B-H analyzers are capable of measuring the magnetic characteristics of these parts, providing data that will facilitate improvement of these materials.
In the case of ordinary ferrite cores, the B-H analyzer can measure inductance characteristics and µ-characteristics.
