Texas Instruments Inc. introduced a new
single-stage LED lighting pulse width
modulation (PWM) controller. The TRIAC-dimmable solution regulates LED current
and also achieves near unity power factor. The reference design can achieve 85
percent efficiency, which enables high-density, small form factor designs. The TPS92210 is designed for general
lighting applications, such as commercial and residential recessed, troffer,
light bulb replacement, architectural and display lighting.
features flexible operation modes such as peak primary current, constant
on-time and frequency modulation. The constant on-time mode provides
single-stage power factor correction for improved efficiency.
cascoded MOSFET configuration results in 10 percent lower switching losses with
fast and easy high-voltage start-up compared to competitive devices.
Continuous linear TRIAC dimming provides flicker-free, uniform control.
Multiple protection features, such as over voltage protection without
optocouplers, thermal shutdown and advanced over current, safely shut down the
system if fault conditions exist.
Programmable fault response, full shutdown and shutdown restart provide added
flexibility for fault response.
By experimenting with the photovoltaic reaction in solar cells, researchers at MIT have made a breakthrough in energy efficiency that significantly pushes the boundaries of current commercial cells on the market.
In a world that's going green, industrial operations have a problem: Their processes involve materials that are potentially toxic, flammable, corrosive, or reactive. If improperly managed, this can precipitate dangerous health and environmental consequences.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
