this paper presents novel active filter for mitigation electromagnetic interference (emi) and other adverse effects of pulse width modulation (pwm) inverter-fed ac motor system. an active filter proposed and devised for this system is characterized by sophisticated connection of two small separate filters, capable of mitigating all the adverse effects. this paper provides high frequency models ...
Electromagnetic interference in pacemakers has almost always been reported in association with the cutting mode of monopolar electrocautery and rarely in association with the coagulation mode. We report a case of electrocautery-induced electromagnetic interference with a DDDR pacemaker (dual-chamber paced, dual-chamber sensed, dual response to sensing, and rate modulated) in the coagulating and...
Abstract Background and Objectives: Incidents related to electromagnetic interference with medical devices have been reported over the past decades. It has also been indicated that the microwave radiation emitted from mobile phones interferes with the operation of medical devices therefore, this study aimed at testing the interference by GSM mobile phones with cell counters. Material and Method...
The EMI filters are usually used for suppression of electromagnetic conducted interference of range 9 kHz-30 MHz. The efficiency of electromagnetic interference filter is described by attenuation characteristics. The value of attenuation of EMI filter depends on main parameters of filter’s elements and its parasitic parameters. Therefore the high frequency model of electromagnetic interference ...
External sources, either within or outside the hospital environment, may interfere with the appropriate function of pacemakers which are being implanted all around the world in current medical practice. The patient and the physician who is responsible for follow-up of the pacing systems may be confronted with some specific problems regarding the various types of electromagnetic interference (EM...
