Single-phase single-stage boost inverter and control method

The invention discloses a single-phase single-stage boost inverter and a control method. The single-phase single-stage boost inverter comprises switching tubes S1-S6, a direct-current bus capacitor Cdc, an input power supply Uin, a first boost inductor L1, a second boost inductor L2, a filter capacitor Cf and a filter inductor Lf. Compared with a traditional interleaved Boost+VSI two-stage scheme, the equivalent switching frequency of the system is doubled, and the input current pulsation rate is reduced, so that the size of a required filter device is reduced, the use of two power diodes is reduced, boosting and inversion control are realized at the same time only through one-stage power conversion, therefore, the system has higher integration level and system efficiency, has the advantages of continuous input current, simple structure, low cost and the like, and also has the capability of inhibiting common-mode current. Therefore, the single-phase single-stage boost inverter is particularly suitable for a h
