Document Type and Number:
WIPO Patent Application WO/2019/084771
Kind Code:
A1
Abstract:
A resonant transformer and a high-frequency electrosurgical equipment using the same, the resonant transformer comprising a primary winding, a secondary winding, and a magnetic core, and being characterized in that the primary winding is divided into m groups, and the secondary winding is divided into n groups; a manner of sandwiched winding is used between such groups of the primary winding and the secondary winding such that the groups are sequentially stacked and same-level windings are not adjacent, wherein m and n are natural numbers. The described resonant transformer and the high-frequency electrosurgical equipment using the same may strengthen the electromagnetic coupling between the primary winding and the secondary winding and prevent the skin effect.
