Editor’s note: PhD candidate, Seyyed Hossein Pishgar approached me with this paper, which I believe has some unique and creative circuitry and architectures. I have ...

Moreover, in battery-driven applications, it is impractical to use linear regulation at varying load points. PWM voltage ... A circuit diagram of a driving motor using a variable DC source.

Very often when simulating an electrical circuit in SPICE ... can be adjusted via an external voltage source. In part one of this article, the variable resistor is examined.
