“…It has relatively good temperature stability, high saturation magnetic flux density, small loss angle and good DC bias characteristics [1–2]. It is widely used as the core of the energy storage inductor, differential mode inductor, transformer and other magnetic elements in the power converter [3–7]. The magnetisation characteristics of magnetic powder cores are non‐linear, and these are affected by stress, temperature, frequency and saturation degree [8–11].…”

It is difficult to measure the magnetisation characteristics of magnetic powder cores with small loss angle and high saturation flux density. Here, a new pulse measurement method is proposed, in which the capacitance with preset bias voltage applies pulse excitation voltage to the measured magnetic component through RLC oscillation discharge, and the air core inductor whose permeability is vacuum permeability is used as the standard magnetic component to eliminate the numerical differential error of the traditional pulse measurement method. Based on the detailed analysis of the measurement principle and error source of the new pulse measurement method, the measurement system is established. The impedance analyser method is used to verify that it can accurately measure the magnetisation characteristics of the magnetic powder core with small loss angle.
