摘要：
A multilevel inverter circuit includes an inverter control circuit that controls switching of main and neutral switches. The inverter control circuit receives current vector information indicating flow direction of an AC current output of the multilevel inverter circuit. The inverter control circuit eliminates dead time between switching of a neutral switch and a main switch depending on whether the AC current output is flowing towards a load or away from the load. Among other advantages, elimination of dead time improves the total harmonic distortion of the sinusoidal AC voltage output of the multilevel inverter circuit.
