Description: 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.
DRIVING PIEZOELECTRIC RESONATORS
The low power EIN-401 Inverter Circuit is primarily intended to drive the 12-15VDC Low Power Piezo Fan Blade at resonance, although it can be used to drive other devices up to ± 15Vp. Circuit components draw very little current.

The EIN-407 Inverter Circuit is used to drive the 100 Hz Piezo Beam Chopper as well as larger Piezo Bending Elementshaving lower resonance values, such as "-503" size benders.

The EIN-408 Inverter Circuit is used to drive shorter Piezo Bending Elements having higher resonance values, such as the "-103", "-203" and "-303" size benders.
