Claim Text:
1. An inverter, comprising: a direct current (DC)-DC conversion circuit, receiving a DC input voltage from a DC input side, and converting the DC input voltage into a DC bus voltage; an inverting circuit, coupled to the DC-DC conversion circuit, and configured to convert the DC bus voltage into an alternating current (AC) output voltage; and an auxiliary power circuit, coupled to the DC-DC conversion circuit, and receiving the DC input voltage from the DC input side, wherein 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 the auxiliary power circuit is enabled, and wherein 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 the DC-DC conversion circuit is enabled, such that the inverting circuit is enabled in response to the second auxiliary power and generates the AC output voltage.
