False Starts: The Story of Vehicle-to-Grid Power

Cars That Think

They wanted to see whether an electric vehicle could feed electricity back to the grid. The company’s president, Tom Gage , dubbed the system “vehicle to grid” or V2G. And EV owners would become entrepreneurs, selling electricity back to the grid. And indeed, that’s how promoters of vehicle-to-grid technology perceive the EV.

Transphorm introduces Gallium Nitride diode; >99% efficient DC-DC boost converter

Green Car Congress

is showcasing a GaN-based, dc-to-dc boost converter running at more than 99% efficiency. Its ARPA-E project seeks to enable compact motor drives and grid-tied inverters operating at high power (3-10 kW) with efficiency greater than 96%. Perreault, MIT). At APEC, startup Transphorm Inc.

The Complex Calculus of Clean Energy and Zero Emissions

Jenkins has also helped push Congress to think more seriously about the power grid, releasing a report last year that showed that much of the 43 percent emissions reduction expected by 2030 would be squandered if the United States doesn’t double the pace of transmission upgrades. power-grid transmission. year grid study from the U.S.

This Clock Made Power Grids Possible

Cars That Think

As more power stations adopted the clocks, the frequency regulation allowed them to share electricity and create an interconnected power grid. And Warren, who eventually solved the grid-frequency problem, was actually working on a different puzzle when he came across the answer. How Warren’s clocks regulated grid frequency Henry E.

He wrote six lessons, which cover transformers, AC and DC motors, magnetism, binary basics, and solar power. In 1969 he was tasked with helping to build transmission lines in Bangladesh that connected the country’s eastern and western electrical grids. He and his family lived there for two years. Zahn, who was granted more than 20 U.S.

The Vacuum Tube’s Forgotten Rival

Cars That Think

An old-fashioned triode vacuum tube does that using a voltage applied to its grid electrode. Amplification occurs because a relatively small DC control current can modify a much larger AC load current. Researchers soon constructed what was called core memory from dense grids of magnetic cores. An amplifier, by. David Schneider.

PHEVLERs are the Zero CO2 Clean Green Machines of the Future

Green Car Congress

The DC and fast charging infrastructures for BEVs are very expensive to construct [ 13 ] & operate, and are wasteful of electricity inversely to the square of charge time (meaning ½ the charge time 4 times the losses, and ⅓ the charge time 9 times the losses). PHEVLERs make our electric grid more efficient. [
