Abstract: Disclosed is a method and standard module for amplifying pulsed power. The key point of the technical solution is as follows: a method for amplifying pulsed power is formed by means of the joint action of a LASER mode of a crystal medium, a carrier multiplication amplification mode of a semiconductor medium, and a plasma breakdown amplification mode of a gas medium. Electric power which is amplified is converted into optical power first, the optical power is amplified again, and the amplified optical power is converted into electric power again by a photoelectric conversion and amplification device. A gas switch is triggered based on a photoconductive switch to generate a timing-synchronized high-power electric pulse. The high-power electric pulse may be directly outputted or distributed in multiple channels to obtain multiple timing-synchronized trigger signals. In combination with pulse charge of a capacitor, multiple timing-synchronized high-power electric pulses are outputted.

Abstract: A device and method for detecting an absolute multi-turn rotation angle. The device includes a housing, a cover plate and a rotating shaft. The rotating shaft is fixed with a main gear, which is meshed with driven gears including a large driven gear and a small driven gear. The main gear is externally meshed with the large driven gear. The driven gears are connected with a two-stage speed reduction device which enables the rotating shaft to rotate multiple circles to slow down to a circle-number gear and enables the circle-number gear to rotate one circle only. Both driven gears and the circle-number gear are provided with bearings. The bearings have magnets therein, and the two magnets are relatively fixed with the driven gears and the circle-number gear, respectively. The top edges of the bearings fit with a printed circuit board, angle sensing chips which are fixed on the printed circuit.
