IGBT Power Stack


SECOMDRIVE MV IGBT Inverter are high performance water cooled converter with Neutral Point Clamped (NPC) topology.
The IGTB Power Stack’s converter can also be used as regenerative converter, e.g. Active Front End (AFE).
SECOM Drive MV IGBT Inverter meets the following requirements:

  • High dynamic performances
  • High power rating at low frequencies
  • Line power factor = almost 1,0 (AFE version)
  • Four-quadrant operation (AFE version).

Grid-side and motor-side converters use 4,8 MVA IGBT modules.
The IGBT Power Stack is a complete three-phase Inverter solution in a single support module (on wheel) and each phase is on a single removable drawer.

Main IGBT Power Stack features::

  • Ready-to-connect
  • Design focused on easy maintenance and quick power module replacement (wheeled power modules allow very fast substitution without any special tool or lifting device)
  • Interchangeable modules, usable on both AFE or inverter unit.
