This article proposes a non-intrusive scheme for real-time monitoring of the dc-link capacitor condition in an ac/dc converter system under low sample rate. The method takes advantage voltage fluctuations on dc side resulting from changes load, without need additional hardware equipment or injection harmonic components. core technology is current integral reconstruction based linear fitting which improves accuracy at sampling rates. begins by introducing targeted this scheme. It then...
High-power laser transmission is affected by aerosol scattering in the atmosphere, beam quality, jitter and other factors, which cause a certain power attenuation during atmospheric transmission. In this paper, model established. Qualitative quantitative analysis methods are used for simulation evaluation. The density of wavelength 1 micron to target calculated, damage effect on different materials also simulated. It provides theoretical basis space application high lasers.
