Hi everyone. I just bought vr 3.1 and I got data for vr3.
communication to and from the module was successful.
training procedure was successful too. but loading the trained voice to recognizer memory was not successful.
checking the status of trained voices returned no trained voice.

I really want to know the importance of the high uf capacitors across the voltage supply of H bridge inverter.
I have worked with and without them but am unable to find a difference in performance of the two situations.
Please kindly put light on this question.
the drain should give a low signal when the gate is charged. connect a bulb to supply positive and the drain. the bulb should light up when u put a gate signal.
circuit values depend on your application. just make sure the current sense resistor doesn't waste too much power. use V=IR and P=I*IR. amplification now depend on what voltage output you want from the opamp at a given sense current.
you may apply the iteration method. put the load and the capacitor then vary the inductor values until the wave becomes a pure sine. use an oscilloscope or get an inductance meter.
