Embodiment Construction
[0067] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0068] When the inverter is working, the DC power supply may have a power frequency or high frequency jump voltage relative to the output negative pole (equal potential with the ground), and due to the existence of the parasitic capacitance of the DC power supply (such as a solar panel) to the ground, it may cause There will be a leakage current problem. The leakage current problem will not only damage the output power quality and reduce the working efficiency...
