the mode of operation of the standard adapters, power supplies, machines that convert alternating current into direct current, strong magnetic fields.

摘要

A power supply (10) and corresponding method (200) supply power in high external magnetic fields. A power converter system (12) converts input power to output power using one or more electromagnetic components (18). One or more ferrous bands (16) encircle the electromagnetic components (18) and shield the electromagnetic components (18) from the high external magnetic fields.
