Resonance Damping Of Lcl Filters Using Capacitor-Current Proportional-Integral Positive Feedback Method For Grid-Integrated Fuel Cell System, Majid Hosseinpour, Amin Kholousi

Emirates Journal for Engineering Research

Nowadays, the use of grid-integrated inverter proton exchange membrane fuel cell (PEMFC) systems is becoming more prevalent due to their efficiency and favorable environmental effects. Switching the grid-connected inverters causes high-frequency harmonics, which are eliminated using LCL filters. These filters are susceptible to instability when their resonant frequency is affected by changes in network impedance. Active damping methods are used to weaken the resonance of LCL filters. However, the grid-connected inverter is prone to be unstable under grid impedance variations due to the negative equivalent resistance resulting by digital control delays. As a solution to this problem, the capacitor-current proportional-integral …

Bureaucratic Politics Run Amok: The United States And Satellite Export Controls, Eligar Sadeh

Space and Defense

The case of export controls of United States (U.S.) commercial satellites is characterized by bureaucratic politics leading to policy outcomes that are not rational, i.e., the desired outcome of national security is not met and commerce in the satellite sector is harmed. The constraints to rational policy making are a result of competition, conflict, and protectionism, the “bureaucratic politics,” among the relevant actors including the U.S. President and Congress, Department of State (State), Department of Commerce (Commerce), and Department of Defense (DOD). It is bureaucratic politics that result in policies for licensing the export of commercial satellites that are far …

The American Bubble: International Traffic In Arms Regulations And Space Commerce, Roger Handberg

Space and Defense

International space commerce in the United States (U.S.) has entered into a period of great uncertainty regarding its current and future competitiveness and marketability of its products. This question arises because the U.S. with regard to space commerce remains frozen in a posture established first during the Cold War. The concern then was that no critical technologies be made available to U.S. enemies and their fellow travelers. The former were obvious while the latter were more problematic since that group also included states with which the U.S. wished to establish more positive relations including international trade. The mechanism used to …

The History Of United States Weapons Export Control Policy, Taylor Dinerman

Space and Defense

All nations regulate Arms sales, but the United States (U.S.) has traditionally gone further than most. After World War I, a conspiracy theory made its way into popular culture that blamed the war, and specifically the U.S. intervention in 1917, on the so called “merchants of death.” Ever since, this has been a powerful and enduring theme in politics and culture throughout the world. Yet, nowhere have the effects of this theory been more enduring than in U.S. policy and law.

You can’t believe everything you hear about the Chinese space program. I worked in Beijing in the late 1990s, and there I encountered a man named Mr. Li. Mr. Li spoke good English, appeared well educated, and claimed to have been in the Chinese Air Force. He would sometimes talk with me about the Chinese space program, particularly about the Chinese space launch facility in Tibet where they were preparing for a mission to the Moon some time before the end of 1999. The purpose of the mission, he said, was to crack open the Moon to allow the Earth …

European Space Policy Update, Richard Buenneke

Four decades after the first autonomous European satellite launch, Europe found itself at a crossroads regarding the course of its security space programs. Facing continued struggles to develop dedicated military satellites at the national level, Europe considered a strategy based on dual-use technology and past successes in civilian launch and satellite programs. This approach centered on a series of “great projects” for navigation, global monitoring, and space situational awareness.

Russian Space Policy Update, William P. Barry

Space and Defense

With the collapse of the Soviet Union in 1992, the Russian Federation found itself the inheritor of much of the Soviet space program. However, this “new”country also had a new leadership that had little interest in a space effort that was viewed as tainted by its close association with the leadership of the Communist Party and its management through the Soviet defense industry bureaucracy. In addition, the extraordinary budgets and priorities assigned to resources designated for space efforts were a luxury that Russia could now little afford. In the face of these enormous challenges, the Russian Space Agency was created …
