Simulation Investigation of a Power Amplifier Circuit for Measurements of Power Losses in Soft Magnetic Materials

This paper presents an investigation of a high frequency power amplifier circuit intended to be used for measurements of power loss in soft magnetic materials. It introduces a description of the envisaged measurement system. Afterwards, simulation investigation of two variants of the amplifier circuit realization is presented where the frequency response of the two circuits is within the focus of interest. The results obtained will serve a reference point in the progress of the dedicated measurement system development.
