Hybrid Flywheel System Extends UPS Run Times with Batteries

A hybrid UPS with a fully integrated energy storage system provides power loss protection by combining flywheel and battery technologies. The VDC XEB supports connected loads with clean backup power that is predictable and seamless....

Controller IC Employs Real-Time Adaptive Loop Compensation, PMBus

Controller IC combines power management and mixed-signal functions that implement adaptive control of closed loop compensation. This SoC consists of a DSP and RISC processor, RAM and non-volatile memory, power conversion blocks, SMBus serial interface, ADC and DAC, and timing sources....

HDBaseT Boosts Home Consumer Electronic Networking

HDBaseT allows transmission of uncompressed full HD digital video, audio, 100BaseT Ethernet, power and various control signals onto a single 100m Cat5e/6 cable. Power over HDBaseT (PoH), a key element of the HDBaseT standard, employs technology similar to PoE with proven capability in enterprise networking. ...

LED Power Management: Techniques Proliferate

There are many power management methods that can be used for LED lighting. You can drive them via a number of dedicated driver ICs available on the market, or even use microcontroller units (MCUs) for more intelligent driving. ...

Optimize Wireless Power Transfer Link Efficiency - Part 2

In Part 1 of this series, we measured the inductance of the transmitting and receiving coils, their respective Q’s near the resonant frequency, and the coupling coefficient of the two inductors, “k”. We showed that the Q, and associated series resistance, RS are significantly impacted by proximity effects of the two coils. ...

Components and Methods for Current Measurement

Current measurement components and methods must provide an accurate output signal as well as preventing damage to the associated printed circuit board.

...

How To Add Analog Dimming To Virtually Any LED Driver

Analog dimming of LEDs has key advantages, including standalone operation, without the need for additional circuitry to generate a PWM signal (such as a microcontroller) and a patent-free environment. ...

Digitally-Controlled AC-DC Supply

A kit employing a dual-thread processor is intended as a production-ready test system tailored to meet the needs of an ac-dc power-supply. This digitally-controlled test supply combines hardware, development software, and example application firmware....
