Abstract: A switching system includes a MEMS switching circuit having a MEMS switch and a driver circuit. An auxiliary circuit is coupled in parallel with the MEMS switching circuit, the auxiliary circuit comprising first and second connections that connect the auxiliary circuit to the MEMS switching circuit on opposing sides of the MEMS switch, first and second solid state switches connected in parallel, and a resonant circuit connected between the first and second solid state switches. A control circuit controls selective switching of a load current towards the MEMS switching circuit and the auxiliary circuit by selectively activating the first and second solid state switches and the resonant circuit so as to limit a voltage across the MEMS switch by diverting at least a portion of the load current away from the MEMS switch to flow to the auxiliary circuit prior to the MEMS switch changing state.

Abstract: A switching system includes a control circuit that receives On-Off signals indicative of a desired operating state of a switch. The control circuit includes an oscillator that generates a first electrical pulse responsive having a first signal characteristic or a second signal characteristic that is determined by the received On-Off signal, which may be related to a frequency or duty cycle of the pulse. A pulse transformer connected to the oscillator receives the first electrical pulse and outputs a second electrical pulse having the same one of the first signal characteristic and the second signal characteristic as the first electrical pulse. A pulse detection circuit in the control circuit receives the second electrical pulse, determines whether the second electrical pulse has the first signal characteristic or the second signal characteristic, and controls transmission of power and control signals to the switch based on this determination.

Abstract: An electrical system includes an operation MEMS switch operable in on and off states to enable and disable current flow to a load and a fault interruption MEMS switch positioned in series with the operation MEMS switch. The fault interruption MEMS switch is operable in on and off states to enable and disable current flow to the electrical load, with operation of the fault interruption MEMS switch in the off state disabling current flow to the load regardless of the state of the operation MEMS switch. A fault sensor control system operate to sense a system variable, analyze the system variable to detect if a fault is affecting the electrical system and, upon detection of a fault, switch the fault interruption MEMS switch from the on state to the off state to interrupt current flowing through the operation MEMS switch to the load.

Abstract: A switching system includes a MEMS switching circuit having a MEMS switch and a driver circuit, and an auxiliary circuit coupled in parallel with the MEMS switching circuit that comprises solid state switching circuitry. A control circuit in communication with the MEMS switching circuit and the auxiliary circuit performs selective switching of a load current towards the MEMS switching circuitry and the auxiliary circuit, with the control circuit programmed to transmit a control signal to the driver circuit to cause the MEMS switch to actuate to an open or closed position across a switching interval, activate the auxiliary circuit during the switching interval when the MEMS switch is switching between the open and closed positions, and deactivate the auxiliary circuit upon reaching the open or closed position after completion of the switching interval, such that the load current selectively flows through the MEMS switch and the solid state switching circuitry.
