Description
Unlike their analog counterparts, digital power supply controllers can benefit from a technique known as Time Division Multiplexing (TDM) to perform more tasks with fewer resources. TDM permits a single processor or “executable” resource to be shared amongst several independent and often unrelated tasks, e.g., software control loops, diagnostics, fault monitoring, etc. In the analog domain, adding additional functions or tasks requires adding additional components. Resource sharing via TDM is possible because digital power supply controllers operate as Time Sampled systems. Designing software to take advantage of TDM for a fully digitally controlled power supply can be a challenge, but by understanding some key principles and following appropriate guidelines, this job can be greatly simplified. In this power seminar topic we will examine how to structure software code to take advantage of a class of low-cost digital controllers.

PRESENTER
David Figoli – David Figoli is currently the Systems and Device Architect for TI's Digital Power Systems group and a Senior Member of the Technical Staff. He completed his BE (Electrical) at UNSW, Sydney, Australia. He joined TI Australia in 1989 and later transferred to TI US (Houston) in 1995 with the C2000 DSP group as Applications Manager. Together with his applications team, he championed the industry's first full modular, digital motor control software library. Since 2002, David has led an effort to deploy Digital Signal Processing (DSP) technology into the power supply market, as an extension to the success of digital control techniques in motors.
