We want our PCS to have components spec’d for a nominal input voltage of 130.68 V
Topology
Idk these are a thing:
...
ZVS is achieved by the above using an active clamp flyback. LLC is another popular ZVS topology, but it only operates at resonance at a fixed buck ratio which may hurt efficiency for us since the pack varies in voltage greatly.
