A cascaded H-bridge inverter builds its output from

  • A.a single bridge with flying capacitors between the legs
  • B.a matrix of bidirectional switches with no dc link
  • C.several single-phase bridges in series per phase
  • D.one bridge per phase with clamping diodes to the mid-point

Answer: C

Each cell contributes its own voltage step and the cells are summed in series, so many levels are available. Each cell needs an isolated dc source, which is why the topology suits drives fed from a multi-winding transformer or from batteries.
