The MLDC waveforms are described here under ideal conditions, i.e. all the DC capacitances are of infinite size, the on-state switches' voltage drop is zero, their off-state impedance is the ith switching angle, m the number of levels and n the harmonic order (which in the simulation results presented here is limited to the 49th order).

Figure 6.12 shows the flying capacitor circuit (also known as floating capacitor or imbricated cell conversion), as well as the corresponding output voltage waveform. The latter is identical to that of the neutral point clamped converter shown in Figure 6.1. In the three-level flying capacitor solution, the additional voltage step is obtained by the use of a separate DC capacitor in each phase; this capacitor is pre-charged to one-half of the total DC voltage across the converter bridge.

In the three-phase configuration shown in Figure 6.14 all capacitors have the same voltage rating and, thus, a series connection of capacitors is used to indicate the voltage level between the clamping points. The capacitors are directly connected to the output through the converter switches and the AC voltage waveform is very much the same as that produced by the diode clamping scheme.
