Research On Coefficient Of ICC Current And Human Being's EEG

More and more power electronics device used in household appliances in modern times may produce many power quality questions such as harmonics and interharmonics. Especially the low frequency of interharmonics which between zero and power frequency is close to the frequency of human being's EEG, which probably results correlation. Therefore, the interharmonics may influence human's healthy. So it is very significant to do the researching of weather there is influence between interharmonics and human being's EEG.This dissertation does the research that weather ICC current influence human being's EEG Integral Cycle Control (ICC) is an efficient voltage reduction scheme that reduces its input voltage to zero in one or more cycles (or half cycles) in a periodic fashion using simple power electronic devices, which can reduce average voltage. This research constructs an experiment flat-top whose load is a resistance to gather the synchronous data of ICC current and EEG The experiment chooses Solid-State Relay as the switch of ICC current and a 16 inputs EEG amplifier, as the same time, the experiment used LabVIEW programming to control the SSR. To gather the synchronous data of ICC current and human being's EEG , we first use current probe to change the current signal into a voltage signal and then input it into the EEG amplifier for the synchronous measurement of the EEG data. After all this, the paper gathered synchronous data of ICC and EEG under different active powers.50Hz power frequency interference in the environment is the main noise of EEG, this paper designs a 50Hz notch filter based on kaiser function . Following this, this paper makes virtual value analysis to the ICC data and makes average value analysis to the EEG data after filtering. After data analysis the paper made correlation analysis, then calculate the correlation coefficient and compare correlation coefficient with the test statistic we choose.Through the above-mentioned analysis may verify that there is certain correlation between ICC current of household appliances and human being's EEG. That is to say that ICC current and interharmonics may influence human being's EEG...
