Illustrative functional conversion ledger through final DC conversion: AC four blocks, integrated MV/DC three blocks
4 → 3 functional blocksderived
| Value kind | derived — Derived values are guide calculations; their result is only as fixed as the stated inputs, scope, and method. |
|---|---|
| Scope | Same final-output boundary, including final DC conversion; an integrated SST contains internal power-electronic stages. Not a universal architecture count. |
| As of | 2026-09 |
| Source | Guide illustrative functional ledger dated September 8, 2026; OCP deployment-path discussion published August 11, 2026, opened September 8. The count is a guide derivation, not an OCP efficiency measurement. · Chapter 4.1 worked conversion ledger; OCP deployment paths A and B. |
| Derivation | AC: transformer, UPS package, rack PSU, final converter = 4 functional blocks; integrated MV/DC: SST package, rack DC/DC, final converter = 3. An UPS/SST package contains internal switching stages. Distribution and auxiliary losses remain explicit. |
