Abstract
A system for testing electromagnetic characteristics of an electromagnetic steel sheet includes: a driving unit operable based on a non-sinusoidal wave control signal from a control unit and a floating voltage to output a control output; a power output unit operable based on the control output from the driving unit to output a voltage output at an output side coupled across a first winding wound around the electromagnetic steel sheet such that an exciting current flowing through the first winding is generated in response to the voltage output, thereby resulting in an induced voltage across a second winding wound around the electromagnetic steel sheet; and a measuring unit outputting to the control unit an output corresponding to the exciting current and the induced voltage measured thereby such that the control unit obtains the electromagnetic characteristics of the electromagnetic steel sheet based on the output.
