Objective: To develop an efficient and low cost adjustable speed drive while minimizing switching frequency and input current harmonic distortion using the PEBB concept.

83 kVA Multilevel Inverter Building Block

1 MVA, 6,000 V Cascaded Multilevel Inverter/Adjustable Speed Drive

  • Features

  • Uses 12 identical multilevel inverter building blocks in cascade to create a 3-phase, 17 level topology;

  • Able to use 1200V IGBTs, while total output voltage is 6,000 V ac;

  • Utilizes a unique configuration to minimize harmonic line current;

  • The 17-level topology allows for low harmonic content at the output at very low switching frequencies;

  • Low dv/dt reduces motor insulation stress
