Control strategy applied on double flying capacitor multi-cell inverter for increasing number of generated voltage levels

摘要: A 15-level flying capacitor multi-cell based inverter with new control method is proposed. The main benefit of this topology minimising the number components (switches, insulated-gate bipolar transistor (IGBTs), diodes, capacitors and DC sources minimum variety number) that are used for producing same output voltage levels. proposed novel strategy capable regulating on desired values, which results in increased Another feature robustness against load changes. Moreover, a algorithm presented determining rating capacitors. Simulations carried out PSCAD/EMTDC software package experimental data were validated numerical results.
