Abstract:
1. A device for simulating a rectified constant impedance load being applied to test a power product, and comprising: an analog-digital converter electrically connected to the power product and configured to convert an output voltage of the power product to a digital voltage value; a digital signal processor electrically connected to the analog-digital converter and configured to let the digital voltage value be applied by a passive load model function for determining a load current value; a digital-analog converter electrically connected to the digital signal processor and configured to convert the load current value to an analog control signal; and an active electrical load module, wherein one end of the active electrical load module is electrically connected to the digital-analog converter and the other end of the active electrical load module is electrically connected to the power product, and the active electrical load module is configured to receive the analog control signal from the digital-analog converter and a rectified voltage, a load currents being produced according to the analog control signal and the rectified voltage.
