Abstract :
A novel power supply is proposed to improve the characterization of soft magnetic materials at high flux density. The power supply consists of a high-frequency switching power supply (PWM inverter) with a voltage regulator to control the distortion of the electromotive force induced in the device under test (Epstein yoke, wound, core, etc.). Experimental results confirm the good features of the proposed solution for flux density values up to 1.9-2.1 T
