S0530106 フィンガー型PSJAのEMI特性に関する研究

抄録

It is considered PSJA (Plasma Synthetic Jet Actuator) is effective for detachment restraint and resistance reduction. And now it is being researched. PSJA is an electric device designed for jet induces that is composed of the two electrodes and the insulator. By applying the ac voltage between electrodes, PSJA induces jet by a discharge of electricity. However, PSJA cause an electromagnetic interference to use an electric discharge and may affect other electric equipment. That is why it is necessary to evaluate the influence of the electromagnetic interference at the time of the PSJA operation. Then, we perform the measurement of the electric field intensity when PSJA is operated. But the measurement in the real use environment is difficult. This is because such as a setting object and a fixed appliance become the antenna under the real use environment. Therefore we decided to evaluate the influence only for the main body of PSJA in this study Spectrum analyzer and dipole antenna is used for the measurement of the electric field intensity. As a result, I confirmed that electric field strength measurements were less than a permission level of the interference wave electric field strength of the class A information technology equipment which association of VCCI established. From this, we confirm that the electromagnetic interference is not caused by the use only for the main body of PSJA
