Abstract

PARD (Periodic and Random Deviation) of controllable power is important to the study on performance degradation of electronic equipment under voltage stress with different PARD. Taking switching power as an example in this paper the PARD signal is analyzed in time domain and frequency domain. We find that it is closer to real situation when peak-peak value (Vp-p) and characteristic frequency are selected as the main characteristic parameters of DC power PARD. At the same time the hardware of voltage with different PARD is implemented using the method of AC superposed DC.
