1. an electronic load device is applicable to emulation one circuit unit, a supply unit is carried out electric power draw a year test, it is characterized in that described electronic load device comprises:

  • One power consumption unit is connected in described supply unit, and it has the mechanism of an adjustable variable current, carries in order to described supply unit is drawn;

    One electric power detecting unit, be coupled between described power consumption unit and the described supply unit, can measure described power consumption unit described supply unit is drawn magnitude of voltage and the current value that carries, and export one first voltage value signal and one first current value signal in a very first time;

    AndOne digital signal processor, store the equiva lent impedance parameter of described circuit unit, described digital signal processor can receive described first voltage value signal and the first current value signal, and according to described equiva lent impedance parameter, calculate out magnitude of voltage and the current value of one second time, and then export an impedance modulating signal to described power consumption unit, with the current value of the mechanism of adjusting described adjustable variable current.
