Title:
外科血管封止用の高周波発生器システム
Document Type and Number:
Japanese Patent JP2013543745
Kind Code:
A
Abstract:
The present disclosure is directed towards systems, methods, and apparatus for providing power for an electrosurgical instrument. In particular, a power supply generating a non-sinusoidal driving voltage having a driving frequency is provided. The power supply provides the non-sinusoidal driving voltage to a series LC circuit having a resonant frequency twice the driving frequency. The series LC circuit configured to present an impedance to limit current. The power supply stores energy in the series LC circuit during each resonant cycle of the series LC circuit. The power supply, during each resonant cycle of the series LC circuit, discharges substantially all of the energy stored in the series LC circuit. The power supply generates a quasi-sinusoidal current in the series LC circuit from the non-sinusoidal driving voltage.
