Low-Power Analog Techniques for Maximizing Battery Life in Embedded-Control Systems.
The heart of portable electronics is the battery, which supplies the electrical energy required to power the internal circuitry. Since the battery performs such a critical role, it is worthwhile to briefly discuss the various battery chemistries currently found in portable devices and some of the characteristics of each. The four main types of battery chemistries currently found in portable electronics include Alkaline, Nickel Cadmium (NiCd), Nickel Metal Hydride (NiMH) and Lithium Ion (Li-Ion).
Shutting down inactive circuitry can save substantial power; however, this kind of power management assumes there is an actively managing brain (typically a microcontroller) that knows when to turn things on and off. In extremely low-power systems running at sub-microamp levels, it may instead be desirable to let the microcontroller remain in a deep sleep mode and use a simple, ultra-low-power clock to wake circuitry at periodic intervals.
Everything under control EPCOS power factor controllers allow complex PFC tasks to be carried out fully automatically. They also ensure that the capacitors switch with minimum wear and can measure a wide range of data at the same time.
Linear Technology | Complete Single IC Power Management Battery Maintenance/Backup System for 48V Supplies
A common trend for electronic devices is increased portability; it is no longer universally acceptable for a device to turn off simply because somebody pulled the plug. In order to implement portable functionality, devices must include advanced power management systems that can control the path of power from available sources to appropriate system outputs, keep a backup element charged and ready, and ensure that a system has adequate power at all times.
Cannons APD series is a typical solution for various engine, transmission, PC board and Junction box application. Customers demand a cost-effective, highly reliable, IP graded, robust connector system for control, power distribution box, and Junction box applications in their vehicles. With customers demanding 500V dc / 20A application, standard APD 4-way cant meet the captioned electrical specification. Therefore, weve designed the new 500V dc APD 4-way with no change in overall dimension / layout with the standard APD.
The worldwide growth in computer server farms and Internet traffic has resulted in this infrastructure consuming global energy production at an accelerating rate. With significant efficiency improvements already attained, attention is now directed to the on-board cooling fans which consume 10% to 15% of the total power used by the server. Transitioning to Allegro three-phase BLDCs for cooling can reduce energy use considerably.
This application note presents the importance of identifying the accurate AC resistance of an inductor, and provides a design example for estimating power losses based on the BournsR Model SRR1206 and SRR1260 inductors. This application note also illustrates that while core losses are still small compared to AC losses in many surface mount power inductors, core losses and thermal effects must be taken into consideration.
