A choke is a coil normally not a too big value, that serves to choke off or filter high frequency signals from the line of interest.
A choke with a capacitor in parallel become a resonant choke, because of resonance the impedance at that frequency become immense dozens of times greater than with the choke alone.
A choke connected in series with a diode being subjected or coupled in a transformer become a charge pump if connected in boost mode.. i don't know if connected in bucking mode... A charge pump mean that it won't have limitation of potential difference, the secondary voltage grows up to the limit. for example a 100v secondary with a diode and a small choke will charge a capacitor up to 3kv... Thats why is so called a charging choke...
If the same situation of last example but the choke not coupled... the voltage only doubles at the resonant frequency...
So what i mean is that a choke don't choke whatever current off it only creates a high impedance path for ac signals...
You are right when you say the higher the current the voltage decreases, because the higher will be the voltage across the coil so it acts reducing the potential applied... hwr its accumulating it on the coil ok---

Voltage is Voltage... If the inductor is a secondary in a transformer is the same thing as a battery is simply has AC instead of DC... Voltages still add or subtract... If you want to understand is up to you...
Just clearing a secondary of a transformer is a battery with alternating polarity that follow a sine function... and has an impedance due to the frequency and its inductance, also other limitations from core limited size, whatever ... A battery also has an analogous impedance the internal resistance...
Any other inductor coupled to the same transformer, has only two options or add or subtract the voltage if connected in series...
