Zusammenfassung: | A drive device 3 includes: a first circuit 5 that connects an alternating current (AC) power supply 100 and a primary winding 351 constituting an output transformer 350 to each other; a second circuit 6 having a pair of electrodes 600A and 600B detachably connected to an ultrasound treatment instrument 2 and having a pair of output lines 610A and 610B connecting a secondary winding 352 constituting the output transformer 350 and the pair of electrodes 600A and 600B; and a third circuit 7A having one end connected to the output line 610A and the other end connected to a ground GL. The third circuit 7A includes: an inductor 720A being a passive element; and capacitors 700A and 710A being passive elements connected in series to the inductor 720A. |
