description A micro inverter having a plurality of independent inputs and a photovoltaic system are provided. The micro inverter includes multiple isolated DC-DC converters and a DC-AC converter. Each isolated DC-DC converter of the isolated DC-DC converters includes an inverter H-bridge, a transformer and a voltage-multiplying rectifier. An input terminal of the inverter H-bridges is configured to connect to a direct-current power supply. A secondary winding of the transformer is connected to an input terminal of the voltage-multiplying rectifier. An output terminal of the voltage-multiplying rectifier is connected to an input terminal of the DC-AC converter. A leakage inductor or an external inductor of the transformer forms series resonance along with a capacitor in the voltage-multiplying rectifier.
