dc.subject.otheran undersampling control analysis and design for DC–DC stages of a single-phase PV converter application. With a complex control algorithm (MPPT trackers, several current and voltage control loops, trigonometrical functions calculation, etc.), the feasible closed-loop bandwidth implemented in DSPs boards is quite limited. FPGA-based control system is a good alternative, although costly and with challenging programming.

local.description.resumoDigital control methods and digital controllers are widely adopted in power electronics applications due to technical and economic advantages against its analog counterparts. Switched-mode power converters with switching frequencies of hundreds of kilohertz to megahertz impose a challenge such as less sampling time in which control algorithm calculations must be realized in digital implementations. Software-based controllers are designed and implemented in code lines executed in general-purpose DSP, being the most preferred digital implementation. Although high-frequency applications with more complex algorithm calculations restrict the maximum allowable sampling frequency, that can be even below the converter switching frequency. The study, analysis and design in such special condition is a main contribution of the paper. Without loss of generality, a software-based digital design under processing speed limitation is developed for two DC–DC power converters that compose a single-phase grid-connected PV converter: (1) a boost converter and (2) a unidirectional power flow DAB topology.
