Miniature photovoltaic inverter

The utility model relates to a miniature photovoltaic inverter, and belongs to the technical field of photovoltaic power generation application. The technical scheme is that: the miniature photovoltaic inverter comprises a crystalline silicon cell component interface (1), an interleaved flyback direct current/direct current (DC/DC) booster circuit (2), a direct current/alternating current (DC/AC) power frequency commutation circuit (3), a filter circuit (4) and a microprocessor circuit (5), wherein the crystalline silicon cell component interface, the interleaved flyback DC/DC booster circuit, the DC/AC power frequency commutation circuit and the filter circuit are sequentially connected, and are connected with the microprocessor circuit. By an interleaving technology, input and output current ripples can be reduced, so that the service life of a capacitor is prolonged, and total harmonic distortion is reduced; and input and output current are shared, so that the copper loss and iron loss of a flyback transformer are reduced. The miniature photovoltaic inverter has the characteristics of high overall power generation efficiency, small size, convenience for mounting, high reliability, suitability for large-scale production, low cost and the like.
