This test set uniquely combines winding resistance measurement, transformer turns ratio, tap changer dynamic resistance, core demagnetization, transformer type detection, magnetic balance, short ...

Matz Ohlen and Peter Werelius of Megger discuss the unique method of winding resistance measurements in transformers and how they are a fundamental importance to detecting potential mechanical and ...

Significant cost reductions and performance enhancements in planar magnetics have been introduced in recent years. These include replacing costly multilayer PCBs with lower-resistance flat coil ...

The low-power (milliwatt) flyback transformer used in a switched-mode power supply (SMPS) needs to be designed with a gap in the magnetic path for maximum power delivery over temperature. Transformers ...

Power-transformer designs minimize weight and cost based on three assumptions: (1) the power source is a sine wave, (2) the frequency is fixed, and (3) the voltage will not exceed a specified maximum.
