Converter assembly
A converter assembly was a technology used aboard  starships for power generation.

In 2266, the starship  was forced to extend its shields around a small class J starship which it had pursued into an asteroid belt. This over-expenditure of power burned out the lithium crystal circuits at the heart of the ship's power, and caused significant damage to the converter assembly, making the institution of a bypass circuit impossible.
