The method of evaluating disturbances for the kit-modules, such as hard disk drives (HD) and memory boards, was proposed by VCCI. The method evaluates disturbances by measuring the current at power supply lines. Although the method does not reflect the evaluation results of the method published by CISPR, the study of the relation between the measurement level of the kit-module method and the level of the CISPR method is important in order to evaluate the effect of the EMI reduction technology at implementation stage. In this report, a comb generator was used as the kit-module, and it was connected to a PC model. The radiated emission from PC model was measured and the relation between the place of the generator and the emission level was investigated. The PC model was constructed with the PCB and AC mains cable. The generator was placed at the HD position or the memory board (MB) position. The PC model with the generator was presented by the wire grid model, and the radiated electric field was calculated. The results indicated that the calculating results presented the tendency similar to the results of a measurement results. The results also showed that the radiated emission level when the generator was placed at the HD position is around 10 dB larger than the level when the generator was placed at the MB position. The study also suggested that the careful design is important to achieve the sufficient shielding effect of the enclosure. |
