STMicroelectronics' 1200V IGBT Series of power transmitters was created to reduce the environmental impact of daily-use equipment such as home appliances, HVAC systems and industrial machines. The transmitter was designed to minimize two major sources of energy loss — conducting and switching.
According to STMicro, the transmitter's lower switching losses were engineered to allow a higher operating frequency, which in turn permits smaller and lower-cost components to power-control circuits. Its compact, industry-standard TO-247 package is intended to save component count by integrating the ultra-fast freewheeling diode required by most circuits.
The IGBT was also designed to survive short circuits lasting up to 10 µsec, making them resistant to common causes of motor-controller failures such as an error in the gate drive signal, shorting at grounding and breakdown of motor phases-to-phase insulation. The goal is to improve motor reliability and save on repair and replacement costs.
New versions of BASF's Ecovio line are both compostable and designed for either injection molding or thermoforming. These combinations are becoming more common for the single-use bioplastics used in food service and food packaging applications, but are still not widely available.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
