Multichannels high voltage programmable driver for piezoelectric transducer.
A complete design of a compact, high voltage, multichannel programmable waveform generator, using an 8 bit microcontroller, 12 bit digital to analog converter, and high voltage operation amplifier, is presented. The user can generate the waveform by several options: classic waveform, calculator, freehand drawing, and using excel or text file. All the waveform data are stored in a nonvolatile memory of the microcontroller. The generator can work as a stand-alone instrument or conjoined with a personal computer. We used this generator as a controller for piezoelectric inertial slider.
