Generator

A surgical system comprising:

• a surgical instrument;
• and
• a generator including:
• a first inductor formed as a primary coil of a transformer;
• a second inductor formed as a first secondary coil of the transformer continuously connected with the first secondary coil of the second inductor the second inductor being connected between a first contact and a second contact, the first contact and the second contact each being connected to a surgical instrument;
• a third inductor formed as a second secondary coil of the transformer, the third inductor being connected between the first contact and a third contact, a polarity of the second contact with respect to the third contact coinciding with a polarity of the first contact with respect to the second contact of the second inductor;
• and
• a capacitor connected between the third contact and ground, and an inductance of the third inductor and a capacitance of the capacitor are adjusted to set a potential of the second contact to be equal to or less than a predetermined value.
