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

摘要

FIELD: electricity.;SUBSTANCE: invention relates to electrical engineering and can be used in medical devices used in high external magnetic fields. When using piezo technology to convert the power of an AC line to an isolated DC power in high external magnetic fields, the power of the AC line is converted by system (10) and method (200) for supplying power in high external magnetic fields (202) to isolated power using one or more piezoelectric transformers (18). Power flow of the AC line to piezoelectric transformers (18) is controlled (204) to maintain an isolated power with a predetermined voltage.;EFFECT: technical result is the provision of an isolated low-voltage DC voltage sufficient for the operation of medical equipment.;10 cl, 16 dwg
