The invention discloses a three phase boost type three level inverter. The three phase boost type three level inverter is characterized in that a circuit type of the three phase three phase boost type three level inverter comprises a direct current bus, a switch tube, a diode, an electric inductor and a capacitor. The three phase boost type three level inverter has the advantages of being used in a buck-boost type occasion under the circumstance that a transformer or a forestage direct current convertor is not needed, small in size, high in efficiency, low in cost, capable of achieving the purpose that amplitude of output voltage is larger than or less than amplitude of input voltage, and high in maximum direct current voltage utilization ratio, needing low direct current bus voltage under the circumstance of meeting the same three phase load or the same three phase grid demands as a traditional boost type inverter, having common mode rejection ability, and being suitable for a middle and high voltage occasion due to the fact that voltage stress of the switch tube is one half of the traditional boost type inverter such as a three phase boost inverter.
