Distributed on-chip voltage regulation offers an appealing solution to many power delivery challenges in modern chip designs. In-depth understanding of such power delivery networks (PDNs) that encompass large on-chip passive power grids and active on-chip and/or off-chip voltage regulators is hampered by high network complexity and the intricate interactions between a multitude of active regulators...
Integrating a large number of on-chip voltage regulators holds the promise of solving many power delivery challenges through strong local load regulation and facilitates system-level power management. The quantitative understanding of such complex power delivery networks (PDNs) is hampered by the large network complexity and interactions between passive on-die/package-level circuits and a multitude...
Desired islanding detection method not only can detect islanding within acceptable duration, but also require it has less adverse impact on power quality. This paper presents an active islanding detection method for a distributed resource (DG) unit which is coupled to a utility grid through grid-connected converter. With the proposed method which is based on adding periodical disturbing current through...
For the mathematical model of PWM inverter under the d-q rotary coordinate system, there exists coupling between the active current and reactive current, which makes it difficult manipulating the power injected into AC grid from distributed generation system. So as to handle the problem, a novel current decoupling strategy based on the input-output linearization is employed in the paper and the PI...
