Power supplies are electronic or electrical equipment, which changes the form of a source of power into the desired form compatible with equipment for which the power supply is used. Medical power supply devices are used in a wide range of medical applications such as MRI, X-ray, CT and PET scanners, patient monitors, blood analyzers, DNA equipment, dental equipment, and robotic surgical devices. Specification and selection of power supplies for medical applications is a task that needs to be executed effectively; especially, due to the frequent changes in the safety and environmental standards for medical equipment. Electromagnetic Interference (EMI) creates significant distortion to the operation of equipment. Medical equipment is more sensitive to Electromagnetic Interference (EMI) as compared to industrial equipment. This, in turn, makes EMC (Electromagnetic Compatibility) with efficient performance a key challenge for OEMs of medical power supply devices.
