摘要： Electrosurgical generator comprises an inverter unit (4) generating a high-frequency alternating voltage to be supplied to at least two output sockets (17, 17') for connection of electrosurgical instruments (19, 19'). The inverter unit is a multilevel inverter. It comprises a plurality of co-operating inverter cells (5-1, 5-2, 5-3, 5-4) which are connected in a cascaded manner in a first state and being split into at least two groups (I, II) in a second state. The inverter unit is selectively switchable between said first and second state. Each group is assigned one of the output sockets and feeds its HF voltage thereto. This enables simultaneous controlling of the distinct groups and their HF output. Unwanted interference patterns can be avoided. Uncontrolled low-frequency beat can be largely suppressed, allowing improved control of thermal energy and cutting power. Quality of the work performed can be increased.

摘要： Ein Elektrochirurgie-Generator für ein elektrochirurgisches Instrument (16) umfasst eine Gleichspannungsversorgung (2) und einen Inverter für Hochspannung, der eine hochfrequente Wechselspannung mit variabler Spannung und Frequenz erzeugt, die an einem Ausgang (14) zum Anschluss des elektrochirurgischen Instruments (16) ausgegeben ist. Erfindungsgemäß ist der Inverter als Multilevel-Inverter (4) ausgeführt ist und umfasst eine Mehrzahl von kaskadiert geschalteten Wechselrichter-Zellen (5), die von einer Steuereinrichtung (41) angesteuert sind. Dank der Kaskadierung sind in den Leistungshalbleitern anfallende Schaltverluste verringert, sowohl in Bezug auf Höhe (durch die aufgeteilte und damit niedrigere Spannung) wie auch in Bezug auf Häufigkeit (durch die verringerte Schaltfrequenz). Dank des quadratischen Zusammenhangs zwischen Spannung und Verlustleistung wird eine überproportionale Entlastung der Wechselrichter-Zellen erreicht. Ferner wird die Dynamik verbessert, da die Wechselrichter-Zellen schnell und gezielt auf Änderungen, insbesondere bei Sprüngen der Lastimpedanz, anpassbar sind. So können stabile Ausgangsspannungen auch bei stark gepulsten Moden erreicht werden, mit zuverlässig vorgebbarem Scheitelfaktor auch bei kurzem Tastverhältnis.

摘要： Electrosurgical generator for providing a dual frequency power output in a low and a high frequency range to an output socket (16) for an electrosurgical instrument (19), comprising an inverter unit configured to simultaneously generate said dual frequency power output. The inverter unit is a multilevel inverter (3) comprising a low frequency driving unit (41) configured for forming a low frequency reference signal, a high frequency driving unit (42) configured for forming a HF reference signal, and a modulation unit (6) configured for forming a modulated combined reference signal by modulating the low frequency reference signal onto the high frequency reference signal. The modulated combined reference signal is supplied to the multilevel inverter for generating the dual frequency power output. Thereby, an efficient way for providing highfrequency energy in the low frequency (ultrasound) band as well as the high frequency (radiofrequency) band by means of a single inverter is formed.
