Abstract: This paper proposes a switched-capacitor multilevel inverter for high-frequency ac power distribution systems. The proposed topology produces a staircase waveform with higher number of output levels employing fewer components compared to several existing switched-capacitor multilevel inverters in the literature.
In many applications, it is important for an inverter to be lightweight and of a relatively small size. This can be achieved by using a High-Frequency Inverter that involves an isolated DC-DC stage (Voltage Fed Push-Pull/Full Bridge) and the DC-AC section, which provides the AC output.
Abstract, aluminum electrolytic and DC film capacitors are widely used in all types of inverter power systems, from variable-speed drives to welders, UPS systems and inverters for renewable energy.
The power supply topologies suitable for the High-Frequency Inverter includes push-pull, half-bridge and the full-bridge converter as the core operation occurs in both the quadrants, thereby, increasing the power handling capability to twice of that of the converters operating in single quadrant (forward and flyback converter).
For three-phase inverters at any DC bus voltage, for films and electrolytics, respectively, a rule of thumb is that about 5 and 50 millicoulombs of capacitor nameplate CV rating will be required per amp of ripple current.
We may infer from Figure 2 that the DC link capacitor’s AC ripple current Icap arises from two main contributors: (1) the incoming current from the energy source and (2) the current drawn by the inverter. Capacitors cannot pass DC current; thus, DC current only flows from the source to the inverter, bypassing the capacitor.
