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

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...

More Information
Summary: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. L'invention concerne un système (10) et un procédé (200) d'alimentation en courant dans des champs magnétiques externes forts. L'électricité en courant alternatif (AC) est convertie (202) en électricité isolée au moyen d'au moins un transformateur piézoélectrique (18). Le flux d'électricité AC vers les transformateurs piézoélectriques (18) est régulé (204) afin de maintenir l'électricité isolée à une tension prédéterminée.
