Resum
Digital control in switching power converters has been proposed and researched in recent years. However, one of the problems which arise in these circuits is that of quantization-induced limit cycle oscillations, which are generally considered to be undesirable. In this work, we investigate the addition of new control terms in the feedback loop of the system, in order to actively prevent these limit cycles from occurring. Firstly, the addition of a sinusoidal signal is considered, and then a mor...
