1. An inverter, which comprises:

  • a DC boosted circuit;

    an inversion circuit connected to an output end of the DC boosted circuit; and

    a bypass circuit, of which an input end is connected to a positive electrode input end of the DC boosted circuit, and an output end is connected to a positive electrode output end of the DC boosted circuit, whereinwhen a DC input voltage applied to the DC boosted circuit is higher than a voltage required by the inversion circuit, the bypass circuit is turned on, and the DC input voltage is supplied to the inversion circuit through the bypass circuit; and

    when the DC input voltage is lower than the voltage required by the inversion circuit, the bypass circuit is turned off, and the DC input voltage is amplified by the DC boosted circuit and then supplied to the inversion circuit.
