The present invention relates to a solar inverter for changing a pulse-width modulation (PWM) method of the solar inverter and a configuration of an output filter to reduce leakage current and a switching loss. To this end, according to the present invention, the solar inverter comprises: a direct current (DC) link capacitor for connecting to a solar module in parallel; a switch unit including first to fourth switches, and operated by a half unipolar switching method; and a reactor of which one side connects to one end of the second switch and the other end of the first switch and the other side connects to a system, and having a preset inductance. |
