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.
