Why an electric vehicle? Environmentalism and the techno-nerd factor are part of it, but it’s mostly economics. I paid $95k (after taxes, registration, etc.) for my Model S, far more than the @$45k I would typically shell out for a car. The federal government nicely handed $7,500 in tax credits and California chipped in $2,500 reducing my Model S cost to $85k. I also have solar on my roof with extra charging capacity that I sell back to the utility so I have credits to cover charging. When I received an appointment at NASA HQ in December of 2016, my wife and I drove the Model S across country to DC and back for free using Tesla’s extensive supercharger network. (Note: “Environmental” NASA had no electric vehicle charging!) No gas bills for 50k miles driven has saved me $5,000 (assume 30mpg and $3/gal). Model S cost down to $80k. Current Tesla buyers aren’t grandfathered into free supercharging and some don’t have solar but it’s still way cheaper than gas. Analysis estimates charging costs at $4.40 per 100 miles, yielding 68mpg equivalency. So, the gas savings for most folks is more like $2,800.

Virtually all commercially available GaN power semiconductors are now lateral devices that can’t handle over about 600 V. New research is focused on producing a vertical GaN structure that’s better for medium- and high-power applications. These are devices where the current, instead of flowing through the surface of the semiconductor, flows through the wafer, across the semiconductor.

5. Old Mike was a conservative-leaning talk radio fan who loved muscle cars. (He has a 1970 Chevelle in mint condition parked in his garage next to his hybrid.) He was not an environmentalist.

The report includes an in-depth analysis of the industrial value chain, which provides a detailed view of the Battery Charger IC Market. The Porter’s Five Forces model for the market has also been studied, in order to help understand the competitive scenario in the market. The study includes market attractiveness analysis, wherein the end-users are standardized, on the basis of the market size, overall attractiveness, and growth rate.

In particular, the IEEE, the technical standards group, issued IEEE-1547, a standard that stipulates how to interconnect distributed resources —like solar inverters—to the electric grid. Currently states are still are deciding whether or how to adopt it. Whitten said the industry supports this standard.

LYNBROOK, NY, FEBRUARY 12, 2019 – Indipro Tools, manufacturers of premium power solutions for digital and professional video applications, will unveil its new Fusion Dual V-Mount Battery Charger at NAB 2019 (Central Hall, Booth 11145). This two-channel lithium-ion charger features two independent charging bays and is capable of simultaneously charging two V-mount batteries at 2.5A each.

“In a lot of scenarios, that demand charge can make up the majority of someone’s bill,” Niles said.

Generally, there is also noise adding to the real and reactive currents of figure 5. In a case where only one known frequency must be analysed in a sampled waveform, the Goertzel algorithm is particularly efficient. In figure 6, a 30 mA rms ‘person leakage´ current is added to a 300 mA rms ‘capacitive leakage´ current with 7.5 mA rms of noise at time = 0.1 s. The visible effect on the total leakage current is quite burried, but after treatment with the Goertzel algorithm the 30mA current step is easily recovered. If this leakage exceeds a predefined threshold value, appropriate action can be taken at the system level.

The H200 is an energy storage solution that integrates lithium batteries and the H5000 hybrid inverter into a 19-in. industrial enclosure. The H200 now offers Panasonic LNMC and Dragonfly LFP as battery options. The wiring terminals have been relocated to the backside of the H200 for easy access and speedy installation. The distribution panel was also redesigned with micro breakers thus making it more compact and increasing the battery bay space to allow up to 30 kWh of battery storage.

GaN and SiC semiconductor materials allow for smaller, faster, more reliable devices with higher efficiency than their silicon-based cousins. These capabilities make it possible to reduce weight, volume, and lifecycle costs in a wide range of power applications. Figure 1 compares the breakdown voltage and on-resistance of Si, SiC, and GaN devices.
