Abstract: A power semiconductor device includes a substrate, a main body and an electrode unit. The main body includes an active portion, an edge termination portion surrounding the active portion, and an insulating layer disposed on the edge termination portion. The edge termination portion includes a first-type semiconductor region, and a plurality of spaced-apart second-type semiconductor segments distributed in the first-type semiconductor region and arranged at intervals along a Y-direction directing from the insulating layer toward the substrate, and an X-direction directing from the active portion toward the edge termination portion. The electrode unit includes a first electrode and a second electrode.

Abstract: A solar generator capable of power tracking and electric characteristic curve measurement and a method for realizing the same is disclosed. The solar generator of the present invention comprises at least one solar panel receiving solar energy, converting the solar energy into electric energy, and outputting the electric energy; an electric tracking-measuring circuit connected with the solar panel and the external load; and a processor connected with the electric tracking-measuring circuit, controlling the electric tracking-measuring circuit to receive the electric energy and output the electric energy to the external load at the highest power. When the illumination on the solar panel is greater than a preset value, the processor controls the electric tracking-measuring circuit to measure the I-V characteristic curve of the electric energy to determine the operation status of the solar panel.
