Abstract
An isolation transformer arrangement has an isolation transformer having magnetically coupled primary and secondary windings, one of which is formed of at least one planar conductive run formed on an associated face of an insulating substrate of a printed circuit board and the other is formed of a number of turns of an insulated wire conductor. The printed circuit board also has one or more discreet electric components arranged in two electrically separate circuits each circuit connectable to a respective one of the primary and the secondary windings of the isolation transformer. The insulation of the wire conductor winding provides a desired level of electrical isolation between the circuits necessary for use in medical equipment.
