  • Abstract The three-level T-type inverter has received much interest in energy storage systems due to its high efficiency. The present thesis proposes a novel modulation for three-level T type inverter fed by two distinct battery banks in series connection as energy storages system. The proposed three-level modulation is able to control charge/discharge current of each battery banks to get SOC balancing. In addition, unbalanced condition of capacitors voltage should be considered in three-level modulation since the battery banks might be in different SOCs. Hereby, the inverter will be able to produce balanced output voltage without low order harmonics even under different voltage. Experimental results are provided to verify the proposed method.
