Drive

A Drive consists of one or more sub components. A Drive always has internal capacitance as well as an Inverter that throttles power to the motor from the DC bus. In addition, some drives will have an Infeed Module and/or Bleeder Module.

Power flow to/from the DC bus is reduced proportionally by the inverter efficiency.
