Control of a Three-Phase Hybrid Converter for a PV Charging Station

ABSTRACT:  

Hybrid Boost converter (HBC) has been proposed to supplant a dc/dc support converter and a dc/air conditioning converter to decrease transformation stages and exchanging misfortune. In this paper, control of a three-stage HBC in a PV charging station is structured and tried. This HBC interfaces a PV framework, a dc framework with a hybrid plugin electrical vehicles (HPEVs) and a three-stage air conditioning network. The control of the HBC is intended to acknowledge most maximum power point tracking (MPPT) for PV, dc transport voltage direction, and air conditioning voltage or receptive power control. A proving ground with power hardware exchanging subtleties is worked in MATLAB/SimPowersystems for approval. Reproduction results show the possibility of the structured control design. At last, lab exploratory testing is directed to show HBC’s control execution.

 CONCLUSION:

Control of three-stage HBC in a PV charging station is proposed in this paper. The three-stage HBC can spare exchanging misfortune by joining a dc/dc sponsor and a dc/air conditioning converter into a solitary converter structure. Another control for the three-stage HBC is intended to accomplish MPPT, dc voltage direction and responsive power following. The MPPT control uses altered gradual conductance-PI based MPPT strategy. The dc voltage direction and responsive power following are acknowledged utilizing vector control.

Five contextual investigations are led in PC reenactment to exhibit the execution of MPPT, dc voltage controller, responsive power following and in general power the board of the PV charging station. Trial results check the task of the PHEV charging station utilizing HBC topology. The reproduction and trial results show the adequacy and vigor of the proposed control for PV charging station to keep up nonstop dc control supply utilizing both PV power and air conditioning framework control.
