I need a circuit designed, complete with equipment list, for an Arduino based circuit that can take a smaller voltage, say 9V, and turn it into a square wave output at approx 75V @ 25mA max.
Different to my last posting of this job, which has unfortunately not been completed (for reasons unknown), I would like a working breadboard of the circuit built and posted to me as well.
More detailed specification for device:
See block diagram attached.
To run from batteries. 9V battery, for example, but could be run from other voltages.
Arduino Uno V3 controlled.
This particular implementation is not a requirement, and is just included as an example of the voltage booster part.: http://playground.arduino.cc/Main/RegulatedPositiveVoltageBooster.
Load requirements: be able to drive 75VDC at 25mA max. Load is variable, but does not change fast.
Boosted output to be Square wave “chopped” at 2-10kHz. Adjustable from Arduino.
Amplitude modulatable 0-75VDC by PWM output from Arduino.
