The embodiment of the invention provides a three-level inversion power unit, and relates to the technical field of electronic power. The three-level inverter power unit comprises: a clamping diode module; the four parallel switch modules are electrically connected with the clamping diode module, each switch module comprises a plurality of parallel electronic switches, and the switch modules are used for converting direct current into alternating current and outputting the alternating current; and the capacitor module is electrically connected with each switch module, and the capacitor module is used for absorbing surge peak voltage generated when the switch modules are switched on and switched off. The clamping diode module and the four switch modules connected in parallel convert direct current to be converted into alternating current, then the power of the alternating current is improved through the multiple switch modules connected in parallel, and therefore the high-power three-level inverter power unit i
