Abstract
A medium voltage variable frequency drive having a 2-high controller configuration with a dual bus system is described. The drive control system includes at least one motor control cabinet housing a fused medium voltage bypass controller, a non-fused transfer controller positioned above the fused medium voltage bypass controller, an extendable output bus coupled to the non-fused medium voltage transfer controller, and an extendable supply bus coupled to the fused medium voltage bypass controller. The drive control system further includes a variable frequency drive cabinet housing a variable frequency drive. The variable frequency drive is coupled to the extendable output bus and a power supply line. The power supply line may be further coupled to the extendable supply bus. The drive control system includes at least one cabling transition cabinet housing cabling between the at least one motor control cabinet, the power supply line, and the variable frequency drive.
