The Inverter Circuit converts a DC input voltage to an AC output voltage for driving low frequency (50 Hz to 450 Hz) piezoelectric devices when a DC voltage is available. The ability to tune the frequency makes it convenient for driving resonant devices such as piezo fans, beam choppers, and benders.
Output frequency is manually adjusted by turning the trimmer pot on the PCB. Optimum tuning is accomplished by observing device amplitude or the output waveform on an oscilloscope during operation. Large input and output terminal pads are provided for clip leads during bench-top testing, and small pads are provided for permanent wiring. #2-56 clearance holes are provided for mounting the board on stand-offs.
