APPLICATION OF PIEZO TECHNOLOGY TO CONVERT ALTERNATING CURRENT LINE POWER TO ISOLATED DIRECT CURRENT POWER IN HIGH EXTERNAL MAGNETIC FIELDS

摘要

A system (10) and a method (200) supply power in high external magnetic fields. Alternating current (AC) line power is converted (202) to isolated power using one or more piezoelectric transformers (18). The flow of AC line power to the piezoelectric transformers (18) is regulated (204) to maintain the isolated power at a predetermined voltage.
