-- The supply converter is a generic device which can convert from |
K |
2 |
-- LV to MV and back, and HV to MV and back. |
|
3 |
-- The machine will not convert from HV directly to LV. |
|
4 |
-- The machine is configured by the wiring below and above it. |
|
5 |
-- It is prepared for an upgrade slot if this is to be implemented later. |
|
6 |
-- |
|
7 |
-- The conversion factor is a constant and the conversion is a lossy operation. |
|
8 |
-- |
|
9 |
-- It works like this: |
|
10 |
-- The top side is setup as the "RE" side, the bottom as the "PR" side. |
|
11 |
-- Once the RE side is powered it will deliver power to the other side. |
|
12 |
-- Unused power is wasted just like any other producer! |
