Power Switch

In the energy sector of Canadian economic and political life, power has a double meaning. It is quintessentially about the generation of power and physical energy. However, it is also about political power, the energy of the economy, and thus the overall governance of Canada. Power Switch offers a critical examination of the changing nature of energy regulatory governance, with a particular focus on Canada in the larger contexts of the George W. Bush administration's aggressive energy policies and within North American energy markets. Focusing on the key institutions and complex regimes of regulation, Bruce Doern and Monica Gattinger look at specific regulatory bodies such as the National Energy Board, the Alberta Energy and Utilities Board, and the Ontario Energy Board. They also examine the complex systems of rule making that develop as traditional energy regulation interacts and often collides with environmental and climate change regulation, such as the Kyoto Protocol on reducing greenhouse gas emissions. Power Switch is one of the first accounts in many years of Canada's overall energy regulatory system.

Is it actually possible? …that we might emerge from this pandemic with a peaceful global power switch from those who have too much to those who don't have enough? With billionaires able to decide the fate of nations, private corporations more powerful and less accountable than ever, and political autocrats around the world shaking our confidence in democratic institutions, power resides in all the wrong places. And so our world is in crisis. In such moments, activists find opportunities. Not to restore the pre-crises order, but to transform it. Paul O’Brien argues that progressive activists may never have a better opportunity to rewrite economic rules, systems and outcomes in favor of those who don't have enough. His book offers practical action steps for activists who want to drive a power switch that overcomes extreme inequalities in our world.

Switch-Mode Power Converters introduces an innovative, highly analytical approach to symbolic, closed-form solutions for switched-mode power converter circuits. This is a highly relevant topic to power electronics students and professionals who are involved in the design and analysis of electrical power converters. The author uses extensive equations to explain how solid-state switches convert electrical voltages from one level to another, so that electronic devices (e.g., audio speakers, CD players, DVD players, etc.) can use different voltages more effectively to perform their various functions. Most existing comparable books published as recently as 2002 do not discuss closed-loop operations, nor do they provide either DC closed-loop regulation equations or AC loop gain (stability) formulae. The author Wu, a leading engineer at Lockheed Martin, fills this gap and provides among the first descriptions of how error amplifiers are designed in conjunction with closed-loop bandwidth selection. BENEFIT TO THE READER: Readers will gain a mathematically rigorous introduction to numerous, closed-form solutions that are readily applicable to the design and development of various switch-mode power converters. Provides symbolic, closed-form solutions for DC and AC studies Provides techniques for expressing close-loop operation Gives readers the ability to perform closed-loop regulation and sensitivity studies Gives readers the ability to design error amplifiers with precision Employs the concept of the continuity of states in matrix form Gives accelerated time-domain, steady-state studies using Laplace transform Gives accelerated time-domain studies using state transition Extensive use of matrix, linear algebra, implicit functions, and Jacobian determinants Enables the determination of power stage gain that otherwise could not be obtained

The energy industry is changing, and it’s far more than just solar panels. Electric vehicles look to overtake gasoline-powered cars within our lifetimes, wind farms are popping up in unlikely places, traders are transforming energy into a commodity, and supercomputers are crunching vast amounts of data in nanoseconds while helping to keep our energy grids secure from hackers. The way humans produce, distribute and consume power will be cleaner, cheaper, and infinitely more complex within the next decade. In The Energy Switch, leading energy industry expert Peter Kelly-Detwiler looks at all aspects of the transformation: how we got here, where we are going, and the implications for all of us in our daily lives. Kelly-Detwiler takes readers to the frontlines of the energy revolution. Meet Steve Collins, an executive from Commercial Development Corporation, the company that blew up two $570-million-dollar concrete cooling towers to create a staging ground for the new $70 billion U.S. offshore wind industry; Rob Threlkeld, a General Motors executive who convinced the auto giant to sign multiple 20-year renewable energy contracts worth hundreds of millions; Kevin McAlpin, a Texas homeowner who buys the power for his home on the electricity spot market – where prices can soar from less than one cent a kilowatthour to $9.00 over the course of a single day; Dr. Kristin Persson, who oversees a supercomputer that can process data at 30 quadrillion calculations per second, in the quest for better renewable energy and battery technologies; and John Davis, a Texas rancher who can keep his land intact, with help from the royalty payments from seven turbines spinning on his range. Energy creation and distribution has driven society’s progress for centuries. Today, people are increasingly aware that it is imperative that humans move towards a cleaner, digitized, and democratized energy economy. The Energy Switch is about that multi-trillion dollar transformation, told from the perspective of those leading us to that bright future.

Push a button and turn on the television; tap a button and get a ride; click a button and “like” something. The touch of a finger can set an appliance, a car, or a system in motion, even if the user doesn't understand the underlying mechanisms or algorithms. How did buttons become so ubiquitous? Why do people love them, loathe them, and fear them? In Power Button, Rachel Plotnick traces the origins of today's push-button society by examining how buttons have been made, distributed, used, rejected, and refashioned throughout history. Focusing on the period between 1880 and 1925, when “technologies of the hand” proliferated (including typewriters, telegraphs, and fingerprinting), Plotnick describes the ways that button pushing became a means for digital command, which promised effortless, discreet, and fool-proof control. Emphasizing the doubly digital nature of button pushing—as an act of the finger and a binary activity (on/off, up/down)—Plotnick suggests that the tenets of precomputational digital command anticipate contemporary ideas of computer users. Plotnick discusses the uses of early push buttons to call servants, and the growing tensions between those who work with their hands and those who command with their fingers; automation as “automagic,” enabling command at a distance; instant gratification, and the victory of light over darkness; and early twentieth-century imaginings of a future push-button culture. Push buttons, Plotnick tells us, have demonstrated remarkable staying power, despite efforts to cast button pushers as lazy, privileged, and even dangerous.

Power Electronic Semiconductor Switches is the successor to Professor Ramshaw's widely-used Power Electronics. The text has been completely re-written and expanded to focus on semiconductor switches, and to take into account advances in the field since the publication of Power Electronics and changes in electrical and electronic engineering syllabuses.
