OREANDA-NEWS. Fujitsu Laboratories Ltd. today announced that it has built the world's first development environment that enhances the efficiency and reliability of the development process for digital controlled power supply units in servers and other ICT equipment.

To deal with the growing complexity of controls as the performance and functionality of power supply units become increasingly sophisticated, the control of power supply units through software has shown significant promise. The challenge, however, has been to increase the efficiency of the software development process in the face of gaps between the performance of actual equipment and simulations in the design phase, increases in coding volumes, and the corresponding increase in software bugs from human error, resulting in an increasing amount of time needed for debugging and testing.

Fujitsu Laboratories has now developed a high-speed, high-resolution I/O board that is able to generate control signals at speeds of up to 150 kHz that are needed to control power supply units, and generate them in complete accordance with models at a high resolution of 150 picoseconds. In addition, by combining the board with automated embedded code generating technology, coding work is no longer needed, and a development environment has been created that verifies the appropriateness of the software control performance for the actual power supply unit and implements it in a microcontroller. As a result, it is possible to cut software development time to roughly one-third of previous methods.
