Abstract: The present invention relates to an electric power converter for converting an input DC voltage into an output DC voltage. The electric power converter includes: an inductor coil (104) connecting a first pole to an input terminal (102) of the electric power converter; a controllable switch (105) between a ground connection and a second pole of the inductor coil; a first one-way conductive component (106) providing a route on a current facing an output terminal (103) of the electric power converter from the inductor coil when the controllable switch is nonconductive; and an overcurrent protecting unit (107) in the output terminal. The electric power converter includes a second one-way conductive component (108) for conducting the current from the input terminal to the overcurrent protecting unit in a defect situation in which the voltage of the output terminal is smaller than the voltage of the input terminal. Therefore, the second one-way conductive component forms a low inductance bypass route on a defect current and enables the overcurrent protecting unit to rapidly react to the defect situation.
