Diodes Incorporated announced a family of pwm controllers designed to improve operating efficiency and eliminate no-load losses. The AP3125 current-mode devices have been optimized for use in offline ac-dc converters in portable products, consumer electronics and domestic appliances. The improvement in performance is a result of the devices’ three operating modes. In normal mode, switching frequency is either 65kHz or
Allegro MicroSystems, LLC announces a new three-phase, sensorless, brushless dc (BLDC) motor controller for use with external complementary P-channel and N-channel power MOSFETs. Reliable sensorless startup and run commutation can quickly be customized for individual motors and loads with adjustment of a few simple default parameters saving considerable design time. The A4963 fits a wide range of applications since the
The Arduino Robot is the first official Arduino on wheels. The robot has two processors, one on each of its two boards. The Motor Board controls the motors, and the Control Board reads sensors and decides how to operate. Each of the boards is a full Arduino board programmable using the Arduino IDE. Both Motor and Control boards are microcontroller
Orion Fans, Inc. has expanded its high airflow fan tray offering to include a front exhaust unit available with up to six-fan positions. Designed for narrow depth cabinets found in security, audio and A/V applications, the OA406 Series ac fan tray combines small size – only 1U high – with reliable performance and high airflows of up to 160 CFM.
Researchers over at Lawrence Berkeley National Laboratory have made a new lithium-ion battery discovery that could prove a little disconcerting to a lot of folks in the energy storage field. The finding comes out of a first-of-its-kind analysis using X-ray absorption spectroscopy, and apparently it contradicts “numerous” studies aimed at improving the efficiency of lithium-ion batteries. The good news is,
Amphenol Industrial Products Groupnow offers a new high current PCB power connector that enables single point power delivery of 150A, 200A and 300A in less than one linear inch of a PCB edge. Amphenol’s RadFin power connectors use RADSOK contact technology to meet the increasing power requirements of printed circuit boards and the need for a smaller board footprint. Designed
Hey, electric-car drivers: Before you get all smug about your green cred, ask yourselves a couple of key questions: Where does the power to juice up your car originate? And what impact does this have on the environment and human health? University of Minnesota researchers looked into this, and their findings are in this week. Electric cars that get their
Optimistic government officials and automakers want to put millions of electric cars on American roads in the next decade. There are a lot of issues to be solved to make that happen (limited range, insufficient infrastructure, high costs, to name the big three), but if we ever get there, we’ll be faced with a new problem: How to ensure the
India is facing down one of the key challenges confronting developing economies: Can it reduce power-sector emissions to curb climate change without hindering economic growth? This challenge became even more pressing when China and the United States, the world’s two largest carbon emitters, agreed to landmark emissions reductions and renewable energy targets. International attention has now turned to India, the
