摘要： A current limiting system for a circuit limits current flow through the system. The current limiting system comprises at least one main switch comprising first and second main switch contacts and a contactor connecting the first and second main switch contacts; at least one current limiting device and at least one solid-state switch, which are mechanically unconnected to the main switch, and the at least one current limiting device and least one solid-state switch are arranged in series on a series side of the circuit; the at least one main switch is on a main switch side of the circuit arranged in parallel with the series side; a control that senses a predetermined condition of the circuit, and operably connected with the at least one solid state switch to open and it. Under normal operating conditions, most current flows through the at least one main switch side. When the predetermined condition causes the main switch to open, and the resistance increases in a main switch side. Thus, current flows to the series side of the circuit side. The current limiting device then switches its state from a low resistance to a high resistance state to limit the current passing through the current limiting system, where the control has sensed a predetermined condition and signals the solid-state switch to open, thereby interrupting current flow through of the current limiting system.

The MEMS gate driver further includes a DC to DC converter electrically coupled to the photovoltaic converter and configured to output a line level DC voltage in response to the DC supply voltage. An electrical circuit, also included as a portion of the MEMS gate driver is electrically coupled to both the photovoltaic converter and the DC to DC converter is configured to receive the supply voltage and the line level voltage and to output a line level drive signal in response thereto.

摘要： A circuit for controlling operation of a load. In one example, a MEMS switch is positioned in the circuit to place the load in one of a conducting state or a nonconducting state. A piezoelectric transformer provides a relatively high voltage output signal or a relatively low voltage output signal to control movement of the switch between a closed position, placing the load in the conducting state, and an open position. The high voltage output signal includes a frequency component in the resonant frequency range of the transformer. Control circuitry provides an input voltage signal to the piezoelectric transformer to provide the high voltage output signal or the low voltage output signal at the output terminals of the piezoelectric transformer.
