“…In this way, a delay is obtained which is equal to the length of the shift-register multiplied by the clock cycle. The total length of the shift-register is at most equal to resol, while each driving signal is extracted from the position obtained by expression (1). The resulting delays are equivalent to the desired phaseshift operation.…”

“…13. The expression of the amplitude of additional harmonics corresponding only to this nonideality can be approached by the expression (10), where the amplitude of the input current is A and the relative difference on the duty cycle is Ad The effects of all the aforementioned nonidealities are shown in Fig. 14. This is a worst-case estimation.…”

“…Digital controllers based on specific hardware, such as field-programmable gate arrays (FPGAs), provide an easy way to genérate many signáis [5], [7], [9], [10], [24], while the accuracy is higher than analog controllers. In this converter, a digital shifter for the pulses has been designed (see Fig.…”

“…Some of the advantages are valid for any application, for example programmability, with decreased number of components, less sensitivity to changes or noise, reduced design time and, more recently, additional power management capabilities, such as Power Management Bus, PMBus [1-2] compatibility or electromagnetic interference, EMI, reduction [3]. Some applications also obtain specific advantages using digital control, such as non-linear control algorithms that seek timeoptimal performance in voltage regulator modules (VRMs) [4][5][6] or interleaving and current sharing in multiphase converters [7][8][9][10][11]. In power factor correction, PFC, most efforts of previous digital proposals have been made attempting to increase the bandwidth of the voltage loop without interfering with the intrinsic output voltage ripple [12][13][14][15][16].…”
