The present invention relates to a multilevel inverter using a signal input voltage source and serial-parallel battery combination. More specifically, the present invention includes: signal DC input voltage source (100); a sub circuit part (200) installed between the single DC input voltage source (100) and a main switching part (300) to transform and output a multilevel output voltage depending on the operation of included devices; and the main switching part (300) including multiple switching devices, connected with both ends of the sub circuit part (200), and outputting an output signal, applied from the sub circuit part (200), through a cascaded H-bridge by determining a pole of the multilevel output voltage when the switching devices are complementarily operated. |
