METHODS FOR ELECTRICALLY ISOLATING A PORTABLE ELECTRICALLY-OPERATED DEVICE AND CONVERTER MODULE FOR PORTABLE ELECTRICALLY-OPERATED DEVICE

摘要

A method for electrically isolating a portable, electrically-operated device, in which a converter module for converting electrical power from an external power source to a desired DC voltage for the device may be adapted to be removeably attached to the device. The converter module may include a switch mode transformer for electrically isolating the external power source from the device.
