description The invention discloses a boost type diode clamping five-level inverter and a working method thereof. The boost type diode clamping five-level inverter comprises a direct-current power supply Uin, a capacitor C, an inductor L, eight switching tubes S1 to S8 and four clamping diodes D1 to D4. Compared with a traditional diode-clamped five-level inverter, the inverter replaces a capacitor on the low side of a direct-current input end with a direct-current power supply Uin, and a boost inductor L is connected between a midpoint o and a point a of an output end of a right bridge arm. In this way, the direct-current power supply Uin, the inductor L, the capacitor C and the switching tubes S5-S8 of the bridge arm on the right side of the inverter form a booster circuit. On the premise of not changing the switching logic of the traditional five-level inverter, an inductor L can be alternately connected in parallel with a direct-current power supply Uin and a capacitor C through switching tubes S5-S8 at the same duty
