Hi,
I have a question concerning a boost circuit Vs a dc motor.
here is a link to a boost circuit:
www.intersil.com/engineeringtools/tools/buckandboostcircuit.pdf
In the step-up circuit, when Q1 is on, L1 is grounded. I feel that
this circuit resembles a lot like an electric motor and its coil.
The analogy is when Q1 is on, it would be like when the brushes makes
contact with the coils. The duty cycles with the time the brushes has
contact with the coils.
I tried implementing this circuit to a dc motor pole and I was not
getting any boosted voltage.The circuit was the same as shown in the
link, but I did not add a load resistance, just a big capacitor. Does
somebody knows why I am not getting a boosted voltage?
There was not filter or smoothing capacitor on the poles of the
motor. I used a small electric motor from a remote control car.
