Power-system designers are continually challenged to maximize the performance of their designs by applying new circuit design techniques and components. But the promise of the “new” can be offset by the perceived risk of trying the “unfamiliar.”...
Digital power solutions make it possible to measure power-stage frequency response in the application, opening the door to new capabilities such as auto-tuning, power-stage diagnosis
and on-the-fly adaptability.
Although the use of digital control eases implementation of the basic power management
requirements, it also affords numerous secondary benefits that can make POL power designs more compact, flexible and efficient.
Power supplies in servers, storage and telecom systems often employ redundant topologies. This means that multiple supplies connected in parallel provide the system power. If one supply fails, the remaining supplies have more than enough capacity...
Despite obvious advantages over analog controllers, the limited power of today's digital controllers requires careful measuring techniques to accurately capture the real-time response of the control loop.
