A predictive estimation based control strategy for a quasi-resonant dc-link inverter

Abstract: Abstract. Control of parallel quasi resonant dc link inverters (PQRDCLI) is usually based on dc link input inverter current. Instead of a direct measurement of this noise sensitive and fast changing current signal -its estimation with one step prediction may be considered. Estimation of an input inverter current is based on inverter output current measurements, applied in most of power electronics controlled ac drives. In this paper, the PQRDCLI fed induction motor (IM) with a predictive current estimation sta… Show more

“…Instead, the selected semiconductors of the converter prototypes have been modeled using their loss models ( Figure 7). With this approach, it is possible to achieve accurate behavior of the circuit schematics which are modeled within a linearized approach [30,31]. The input to output parameters of the physical sample of MPPT converter are as follows (these parameters have also been defined for the simulation model): As shown in Figure 7, the designed model also uses the MPPT algorithm control together with models of photovoltaic panels.…”
