A photovoltaic inverter includes an input circuit, a decoupling circuit and an output circuit. The input circuit has a DC input port, an input capacitor, a magnetizing inductor, a first unidirectional element and a first switch. The magnetizing inductor forms first and second connection nodes. The decoupling circuit has a second unidirectional element, a second switch, a third switch, a third unidirectional element and a decoupling capacitor. The second unidirectional element and the second switch are connected in series at a first node. The third switch and the third unidirectional element are connected in series at a second node. The output circuit has a transformer, a fourth unidirectional element, a fourth switch, an output capacitor, a fifth switch, a fifth unidirectional element, an output inductor and an AC output port. The transformer includes an input port and first and second output ports. A control method of the inverter is disclosed. |
