Valence electrons, power electronics: Which is the best?
Posted July 20, 2018 12:19:11 The best electric power electronics for the home or office are all electric-driven, according to a new study by the Institute for Electrical and Electronics Engineers (IEEE).
This year’s International Electrotechnical Congress (IEC) conference was a key event in this evolution, with the results of a panel discussion on the subject being presented.
“The IEC has long been a forum for discussions about what is the right choice for the workplace,” said Joon-Ho Kang, chair of the IEEE committee that led the research.
IEC was first convened in 1979, but the term “electronics” is no longer used to refer to a single product or group of products, but rather, to a wide variety of products with various levels of performance, energy efficiency, safety and cost. “
We were able to look at the entire range of electric-drive technology and come up with a set of recommendations that are representative of the best electric-driver solutions, in order to give people an understanding of the different types of options for power electronics.”

“There’s a new focus in terms of using the term ‘electronics’ to describe what’s available for the future,” said Jim Silliman, IEEE’s director of policy and advocacy.
“Electronics is a very broad term, and it encompasses a lot of different types, and in fact, this is one of the ways in which the IEC gets involved in discussions about future technologies.”
Power electronics, or “electrodes,” are an essential component of electric vehicles and smart grids, which provide a form of “demand response” to energy-intensive tasks such as lighting and heating, or to the grid itself.
“Electric motors and batteries are key to smart grids,” said Kang.
So the IEEE researchers, along with researchers from the United Kingdom, Australia, Germany, Norway and Switzerland, examined the performance of more than 600 power electronics from various manufacturers and examined the relative benefits and costs of different configurations. “
For many years, they’ve been the standard for energy storage, but they’ve not been the preferred solution because they require more power than what a typical battery can provide.”

“Most of the data points were from the U.S., where they used data from the latest generation of electric motors,” said IEC vice president and executive director Tom Kappelman.
“But we also looked at data from Europe, and the U,K., Australia, and Germany, and we also used data on new battery technologies from Japan, China and South Korea.”
Kappelman said the IEM was “a really important gathering for this type of research,” adding that “this is the first report on the topic in 20 years.”
In this study, the researchers looked at the performance and cost of six different electric-electric drive (EDD) systems from different manufacturers.
They then looked at four different power electronics configurations: the Valence E1, E1A, E2, E3 and E4.
The results are in the June issue of IEEE’s Journal of Power Electronics.
Power electronics can be categorized into two types: “plug-and-play” and “plug and play hybrid” systems.
Plug-and play systems use plug-and charge batteries to provide energy to a plug on the home network, and these batteries can also provide electricity to a connected garage, a mobile home, or other areas.
“Hybrid systems are based on the idea that the plug is connected to a power source, but it is powered by the grid,” said Sillimans research coordinator, Eric Schmitt.
“You have two power sources: one that’s a plug and one that is an electric motor.
The system will deliver power to the power source and that’s what the batteries do.”
Plug-in hybrid systems have a battery that provides electricity to the home, but then also provides power to another home, to the battery’s own charger, or possibly to other devices.
“This is a hybrid that can provide a battery for a home network and a home-grid network,” said Schmitt, “but it’s not a plug-in system.
This is the type of hybrid system that we’re interested in looking at because it offers the highest efficiency and lowest cost.”
The Valence Electric-Drive E1 is the most efficient and the least expensive electric-electronic power system available, said Schimps co-author and IEEE professor of electrical engineering, Mark Bowers.
The E1E1 uses an integrated electric motor with a single battery to provide up to 8 kilowatts of power, while the E1 uses four batteries, each providing up to 2 kilowatt of power.
