1. A circuit for controlling operation of a load comprising:

  • a MEMS switch positioned to place the load in one of a conducting state or a nonconducting state;

    a piezoelectric transformer having a resonant frequency range with a resonant frequency and configured to provide a relatively high voltage output signal or a relatively low voltage output signal from output terminals thereof to control movement of the switch between a closed position, placing the load in the conducting state, and an open position, placing the load in the nonconducting state, the high voltage output signal including a frequency component in the resonant frequency range of the transformer; and

    control circuitry for providing an input voltage signal to drive input terminals of the piezoelectric transformer to selectively provide the high voltage output signal or the low voltage output signal at the output terminals of the piezoelectric transformer.
