Grid-connected inverter is an important part of the grid-connected system. Compared with the traditional L or LC filter, LCL filter has a better high-frequency harmonic attenuation performance. However, LCL filter has resonant peak, which has a great influence on the stability of the system. This paper first analyzes the effect of passive damping method on the resonance peak; then a double closed-loop...
We study the problem of joint spectrum and storage resource backup (JSSRB) to improve the survivability of elastic optical datacenter networks (EODNs) for cloud services. An ILP model and heuristic algorithms are developed. Simulation results show that JSSRB can effectively improve the survivability and spectrum efficiency of EODNs.
We propose a shared protection scheme based on the sharing principle among multiple end-to-content backup paths in optical datacenter networks. Numerical results show it can reduce wavelengths consumption while ensuring the survivability against multi-failures.
Traditional IGBT turn-on loss evaluation methods are curve fitting of double pulse test data without insight of IGBT turn-on process. This paper proposed an analytical evaluation method of IGBT turn-on loss. In the proposed method, a qualitative IGBT switching waveform and an IGBT switching trajectory in output characteristics are used to analyze IGBT turn-on process. The detailed expressions for...
