Step Charge as a function of Pulse Period

Here we can see the Cell Driver Circuit puling a double cell in parallel. The arrangement is powered by a 12V ATX supply. The Cell Driver's inputs: Vcc and Vee are both B+ 12VDC REG. 

This inductor appears to be playing the role of Vc2. When I introduce Vc1 (the other side of the core at 612mH) all modulation and/or rise is completely dampened. 

Too large of an inductance at the Vc2 position (in this specific arrangement), dampens out all modulation.

Too large of an inductance in a Vc1 position also significantly inhibits modulation, unless sufficient offsetting capacitance is added in the form of parasitics, distributed coupling or external parallel capacitance.
