Efficient reduction of EMI from massage and its improvement

Electromagnetic (EM) power disturbance from massage may hurt operators even living environment. EM disturbance from power, transformation, indicator and MOS units in massage were discussed, using on-line positioning and analyzing methods. Test results show that the EMI power emission from massage is reduced, and below the limit values of the relevant standard, by promoting relevant circuits, which will supply some valuable reference further improving electrical and electronic products design.
