Control of switch-mode power converters, which has been traditionally carried out using analog circuits, is nowadays preferably performed digitally due to greater flexibility, higher integrability, less sensitivity to thermal changes, lower costs and possibility to implement advanced control techniques and, for these reasons, it has become a major research focus in power electronics field. Despite the mentioned advantages digitally controlled power converters could cause the onset of non-linear issues due to inherent quantization effect of analog to digital converter (ADC) and digital pulse width modulator (DPWM) which converts the controller output from digital into analog signals. Such quantization effects cause steady-state limit cycle oscillations (LCOs) that are a major concern.
