PROBLEM TO BE SOLVED: To improve a load current frequency response characteristic of an electronic load device with respect to an electronic power unit to be tested. SOLUTION: By serially attaching an inductance L1 to a source of a transistor Q1 for load current control, the frequency response characteristic of an electronic load control loop and an electronic load transient response characteristic at a start of the electronic power unit to be tested are improved, and a circuit means by a nonlinear element is provided between input-output of an operational amplifier for transistor driving of a control circuit. By this, a favorable load current control characteristic is provided in a wide load current range. COPYRIGHT: (C)2005,JPO&NCIPI
