We propose a new three-level inverter based on switched capacitors to solve the problem of conventional multi-level inverters, which do not have boosting capability and self-balanced capacitor voltage. In contrast, the proposed inverter has lower voltage stress than the general switched-capacitor multi-level inverter.
Then, the switched capacitor is chosen to build a multi-level inverter with boosting capability and self-balanced capacitor voltage. For example, in Ref. , Ye proposes a three-phase switched-capacitor multi-level inverter (SCMLI) to achieve both goals. In addition, the SCMLI has a higher voltage gain in Ref. .
For example, in Ref. , Ye proposes a three-phase switched-capacitor multi-level inverter (SCMLI) to achieve both goals. In addition, the SCMLI has a higher voltage gain in Ref. . However, the voltage stress of power switches in their output bridge is several times that of the DC-source voltage.
The circuit outputs a current with RMS of 1.4 A and THD of 5.4%. The voltage of capacitor is measured as 49.2 V and close to Vdc (50 V). Therefore, in this state, the inverter operates stably and the voltage of capacitor can be balanced automatically.
