A battery of constant voltage is in series to a conductor that is placed in a changing magnetic field over time, inducing an EMF with a polarity as indicated in the circuit as "Induced EMF(1)", both the battery and the induced EMF(1) are in series as the input voltage to the DC converter, the intention is to increase or decrease the applied voltage and ultimately the current(if there is a load). The outputted voltage( BAT + Induced EMF(1)) is opposed by Induced EMF(2) that is exactly the same in magnitude to the induced EMF(1), both I-EMF(1) AND I-EMF(2) are induced at the same time. I'm confused as to how things would turn out due to the converter, in a general sense what might happen? Circuit schematic: If I excluded the DC converter like so: It would be easy, the net voltage would be: BAT + Induced EMF(1) - Induced EMF(2) = BAT. Since the Induced EMF(1) = Induced EMF(2). However, what if the convert is in between as the first schematic? And lets say the inputV(to the converter circuit)>outputV or vice versa intputV < outputV? The result is the same? This thread & question are to touch base on the understanding and knowing limits of a DC converter when in a complex and odd situation of induced EMF's or to be exact varying voltages as input and opposing voltages and such. I hope the circuit is clear, I'm new to circuitry still so... I copied this circuit from a source as a reference and aid.
