Light-operated semiconductor switch

Abstract

The invention discloses a light-operated semiconductor switch. A shielding ground electrode, a chip semiconductor laser, a laser beam splitting coupler, a large-area semiconductor unit and a shieldinghigh-voltage electrode are sequentially arranged in the light-operated semiconductor switch from top to bottom. An electricity taking module or a boosting module is connected in a gap between the chip semiconductor laser and the laser beam splitting coupler; the side face of the light-operated semiconductor switch is wrapped with an insulating packaging shell, and the insulating packaging shell and the shielding electrode jointly form a light-operated semiconductor switch packaging shell. A power supply and trigger signal interface of the light-operated semiconductor switch extends out of thelight-operated semiconductor switch packaging shell. According to the invention, the light-operated semiconductor switch can be used for various occasions such as a high-power pulse power supply, a compact high-power pulse assembly, small-size high-energy pulse triggering and the like, and has the advantages of high power capacity, high reliability, long service life, small size and the like.

Description

technical field [0001] The invention belongs to the technical field of pulse power, and in particular relates to a light-controlled semiconductor switch. Background technique [0002] As high-power pulse power supplies and high-power pulse components have put forward requirements for long life, fast frontier, high reliability, and compactness, new solid-state switching technologies with such advantages are very important. The existing electronically controlled power semiconductor switch cannot be separated from the trigger structure and the main circuit structure, resulting in poor withstand voltage level, reliability, and anti-peak ability, which limits its application in high-power applications; the existing light-controlled thyristor , its turn-on speed is slow, and cannot be applied to pulse power applications; the existing photoconductive switch largely depends on the pulse charging auxiliary system or a large-volume laser system, and cannot meet the requirements of min...
