Abstract
Expensive equipments are usually necessary for the measurement of inductor characteristics in power converters. This paper proposes a simple measurement method without using them. It is composed of a coil to detect the voltage, a resistance to detect the current and an Excel file with a macro program for the Fourier analysis. The loss characteristic and B-H curve are outputted automatically using the proposed method. The inductance, resistance, iron loss and harmonic copper loss of an inductor are measured and discussed theoretically.
