This paper proposes an integration fault diagnosis approach of signal-driven method and data-driven method for threelevel inverter feeding induction motor under open-loop v/f *** current paths are analyzed under the normal case and open-circuit fault cases in the IGBTs.A method combining signal-driven and data-driven is *** average values of the positive and negative currents and the ratios are used to be the input features of a two-layer feedforward neural *** are carried out at different speed and load conditions,which verify the effectiveness of the proposed method.
