Multi-resonant electrosurgical generator

Abstract

A multi-resonant therapeutic transformer includes N 1 branches coupled to a voltage source and ground, each branch including two transistors; the two transistors of each branch including a high side transistor coupled to the voltage source and a low side transistor coupled to the high side and ground transistor; the multi-resonant therapeutic transformer includes N resonant tanks each coupled to a respective branch of the N 1 branches and a coil; the coil is further coupled to one of the N branches 1; the first resonant tank is associated with a first operation and the second resonant tank is associated with a second operation; the coil is selectively fed with the first and second resonant tanks based on states of the N 1 branch transistors.
