Abstract: An inverter and a power supply method thereof and an application thereof are provided. The inverter includes a DC-DC conversion circuit, an inverting circuit and an auxiliary power circuit. The DC-DC conversion circuit converts a DC input voltage into a DC bus voltage. The inverting circuit is configured to convert the DC bus voltage into an AC output voltage. The auxiliary power circuit is enabled in response to the DC input voltage, and the auxiliary power circuit generates a first auxiliary power for enabling the DC-DC conversion circuit after being enabled. The DC-DC conversion circuit is enabled in response to the first auxiliary power, and the DC-DC conversion circuit generates a second auxiliary power for enabling the inverting circuit after being enabled, such that the inverting circuit is enabled in response to the second auxiliary power and generates the AC output voltage.
