A power extraction circuit of the secondary circuit is used for extracting power from the secondary circuit and supply the power to a driving circuit, which is used for controlling the turning-on or turning-off of bridge arm switching transistors.

When the high-level input voltage of the driving circuit is above or equal to the preset high-level voltage threshold, the primary switching transistor, the upper bridge arm switching transistor, and the lower bridge arm switching transistor are controlled to switch between on and off states, such that a voltage is normally output. In this way, by means of controlling a micro-inverter to switch working states, it is ensured that the micro-inverter can operate normally when needed.
