PROBLEM TO BE SOLVED: To provide an electrosurgical generator.SOLUTION: An electrosurgical generator 20 includes a controller 24 configured to generate a first pulse train having at least one first control pulse and at least one first reset pulse, and a second pulse train having at least one second control pulse and at least one second reset pulse. The at least one first and second control pulses are asynchronous and the at least one first and second reset pulses are synchronous. The electrosurgical generator also includes an RF output stage 28 which includes a first switching element and a second switching element. The at least first control pulse and second control pulse are configured to activate the first switching element and second switching element, asynchronously, to generate a non-continuous RF waveform. Also, the at least first reset pulse and second reset pulse are configured to synchronously activate the first and second switching elements, respectively, to reset the RF output stage. |
