Toshiba America Electronic Components Inc. (TAEC) has released three high-voltage three-phase motor drivers with built-in power management circuits. The circuits were designed for direct current brushless motors, air conditioner fans and pump motors. Developed by Toshiba Corp., the TPD4104K, TPD4111K and TDP4112K single- chip inverter ICs are manufactured using high-voltage silicon on insulator trench isolation process.
The motor drivers were created to help with energy savings. “A growing number of home appliances and industrial products are employing dc motors and inverters that take lower power consumption and protection of the global environment into account,” says Ajay Chinai, business development manager, discrete products for TAEC. “With these devices, Toshiba is responding to industry demand for higher power, faster response time and higher levels of integration, all in a small structure.”
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
The age of touch could soon come to an end. From smartphones and smartwatches, to home devices, to in-car infotainment systems, touch is no longer the primary user interface. Technology market leaders are driving a migration from touch to voice as a user interface.
Soft starter technology has become a way to mitigate startup stressors by moderating a motor’s voltage supply during the machine start-up phase, slowly ramping it up and effectively adjusting the machine’s load behavior to protect mechanical components.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
If you’re developing a product with lots of sensors and no access to the power grid, then you’ll want to take note of a Design News Continuing Education Center class, “Designing Low Power Systems Using Battery and Energy Harvesting Energy Sources."
