  • Patent number: 9877771
    Abstract: An electrosurgical system includes an electrosurgical generator, a power source configured to deliver power to at least one load connected to the generator, a master configured to generate an initial pulse, and a plurality of slaves connected in series to the master. The initial pulse cooperates with a first floating power supply configured to create an electrical connection between at least one first load and the power source. A first slave is configured to generate a subsequent pulse based on the initial pulse. The subsequent pulse cooperates with a second floating power supply configured to create an electrical connection between at least one second load and the power source. The subsequent pulse is configured to cause an ensuing slave to generate an additional pulse. The additional pulse cooperates with a corresponding floating power supply configured to create an electrical connection between at least one additional load and the power source.

  • Patent number: 8382751
    Abstract: A method for minimizing current draw on a power source for an electrosurgical system includes the step of generating a first pulse signal from a master device to electrically cooperate with a first floating power supply configured to create an electrical connection between one or more first loads and a power supply. The method also includes the step of triggering an ensuing pulse signal from a slave device based on the first pulse signal to electrically cooperate with a subsequent floating power supply configured to create an electrical connection between one or more subsequent loads and the power supply.
