The DC link capacitor also provides a low-impedance path for ripple currents generated by power switching circuits. Figure 1: In a switching power supply, the DC link capacitor is placed across the positive-to-negative rails after rectification (top). In a DC to AC power inverter it is placed in parallel with the input (bottom).
Flying-Capacitor Inverter
One advantage of the flying capacitor-based inverter is that it has redundancies for inner voltage levels, that is, two or more valid switch combinations can synthesize an output voltage. Table 12.2 shows a list of all the combinations of phase voltage levels that are possible for the six-level circuit shown in Fig. 12.6..
Power inverter
A power inverter, inverter, or invertor is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC). [1] The resulting AC frequency obtained depends on the particular device employed. Inverters do the opposite of rectifiers which were originally large electromechanical devices converting AC to DC.
