Claim:
1. A medium voltage drive system comprising: a plurality of modular cabinets, each modular cabinet including a transformer bay to house at least one transformer to couple between a utility connection and a plurality of power cells, the at least one transformer having a core with a plurality of columns each adapted along a horizontal axis, each column corresponding to a phase, where each phase includes a primary winding and a plurality of secondary windings concentrically adapted about the column horizontal axis such that the at least one transformer has a horizontal configuration, and a power cell bay including a plurality of cell chambers each having a protective enclosure in which to house a corresponding one of a plurality of power cells, each of the protective enclosures including a plurality of insulative members adapted in an interlocking configuration to insulate the corresponding power cell, the plurality of cell chambers each having a power service bus to couple the corresponding power cell pluggable to a first face of the power service bus with a second portion of the power cell chamber, the power cell having a plurality of switching devices on a first side thereof, a plurality of rectification devices on an opposite side to the first side, and a low inductance path coupled between the switching devices and the rectification devices, the second portion having a DC link including a power capacitor coupled to a second face of the power service bus, the power cell separate from the second portion, and a cabinet controller bay having a cabinet controller to receive reference control signals from a master controller.
