Electronic load apparatus

An electronic load apparatus, adapted to couple to an electric power device under test by an upper loop and a lower loop, the electronic load apparatus comprising:

• a voltage-dividing circuit coupled between the upper loop and the lower loop;
• a plurality of power components and a current sensing circuit, coupled between the upper loop and the lower loop and sequentially series-connected;
• and
• a control circuit coupled to one of the power components and coupled to the current sensing circuit,
• wherein an enhanced driving circuit is coupled between the voltage-dividing circuit and each of the other power components and adapted to amplify the preceding current to a succeeding current in a preceding region according to a preceding current received from the voltage-dividing circuit and by inputting an external electric power of the enhanced driving circuit, and then in a succeeding region of the enhanced driving circuit a voltage generated according to the succeeding current is applied to the corresponding power component.
