Linnea Brush, Senior Analyst with Darnell Group, revealed the leaders in digital power for 2007 in the report “Digital Power Electronics: IC and Power Converter Benchmarking Survey”. ...
In 2005, I presented a conference paper in which I argued that the power-supply industry would only switch from analog PWM controllers to fully digital controllers if a killer application were found. Here it is two years later and the killer app has yet to be identified — but why?...
Emerging government policies in Asia, Europe and North America are expected to help drive the adoption of digital power technologies, according to the latest analysis from the Darnell Group....
System-on-a-chip features programmable flexibility to configure embedded applications controlled by powerline communications, such as lighting, industrial control, automatic metering, home automation, and smart energy management....
MICROCHIP TECHNOLOGY'S 16-bit Digital Signal Controller (DSC) ICs were hailed as the next generation of digitally controlled power-supply ICs in 2006...
Digital power control has been touted as a means of making controllers more configurable and adaptable to diverse power system requirements. That idea...
Power-system designers are continually challenged to maximize the performance of their designs by applying new circuit design techniques and components...
Using digital-loop control, a PWM controller minimizes
duty cycle to optimize efficiency of a single-phase
synchronous buck converter and boost current delivery....
Using LabVIEW software, analog designers can implement
digital power control without writing VHDL code as

Ericsson: Power Supply Goes Digital
This primer on digital technology discusses conceptually how digital control inside an on-board power supply facilitates improved efficiency, reduced total cost and advanced system power management. Paper includes discussion on the role of PMBus, different approaches to implementing digital control, and a glossary of common used terminology....
Astec Power:: An Introduction to Digital Control of Switching Power Converters by Geof Potter As the author explains in this white paper from April of 2004, “Applying digital methods to the control of power converters, in particular board-mounted dc/dc converters, offers a rich set of possibilities from which to create new features, improved performance, and much greater product flexibility, and all at lower cost.”...
Astec Power: Digital Power, A Manufacturer’s View by Geof Potter
In July 2004, the author heralded the arrival of digital power technology saying, “The fact that we are all gathered for DPF’04 is an acknowledgement that digital technologies have begun to take root in that bastion of analog creativity called a Power Supply. Having, years ago, surrendered our beloved smooth-flowing linear systems to the harsh reality of bi-stable design, we now find ourselves threatened with even more bi-stable process encroachment in the form of digital control systems.” ...
