Abstract
A galvanically isolated switch system and method comprising a plurality of switches having at least one terminal in series electrical connection, at least one control input electrically connected to at least one of the plurality of switches, wherein the at least one control input is isolated from direct current voltages and at least one passive component connected across the plurality of switches.
Claims20
A method for switching a signal comprising:
- actuating one or more of a plurality of serially-connected, galvanically isolated switches, each switch having at least two terminals, in response to a control signal, wherein the control signal is received at a control input that is galvanically isolated from direct current voltages;
- actuating at least one bleed circuit electrically connected between the at least two terminals of at least one switch of the plurality of switches;
- transmitting at least one data signal from one or more of the switches as a function of the control signal;
- and
- transmitting at least one power signal from one or more of the switches as a function of the control signal.
