Selection of Digital Controller for Power System and Power Electronics Applications

Power converters exhibiting higher efficiency, faster response and better control is need of the day. Sophisticated control algorithms are required for the implementation of these converters. This has increased the use of digital controllers in power system and power electronics applications. Selection of a digital controller for power control application is a challenge as there are variety of architectures, specifications, development platforms and design requirements. A right selection is possible only if the application requirements and digital controller capabilities are exactly known. This paper is an attempt to discuss the different aspects of digital controller required for power applications. In initial part of the paper, review of various power system and power electronics applications requiring the digital controller has been taken while the later part of the paper discusses about digital controller specifications to be considered.
