In this work, different sizes of BaTiO3 (BTO) were characterized. The effective parameters were studied to reach optimum performance in order to realize an optical modulator. The parameters such as spectroscopy, electro-optic coefficient, crystalline structure, and birefringence indicated that BaTiO3 has an excellent behavior to manipulate the light by Pockels modulator, spatially in the field of telecom. The sample size (10×3 mm) was shown a good performance compare with other samples, for example, the BTO has low absorption, high variation of output as a function of voltage applied and good efficiency that showed by figure of merit. In addition, a low half-wave voltage (Vπ) was observed.

This study developed a novel, high-efficiency, high step-up DC–DC converter for photovoltaic (PV) systems. The converter can step-up the low output voltage of PV modules to the voltage level of the inverter and is used to feed into the grid. The converter can achieve a high step-up voltage through its architecture consisting of a three-winding coupled inductor common iron core on the low-voltage side and a half-wave voltage doubler circuit on the high-voltage side. The leakage inductance energy generated by the coupling inductor during the conversion process can be recovered by the capacitor on the low-voltage side to reduce the voltage surge on the power switch, which gives the power switch of the circuit a soft-switching effect. In addition, the half-wave voltage doubler circuit on the high-voltage side can recover the leakage inductance energy of the tertiary side and increase the output voltage. The advantages of the circuit are low loss, high efficiency, high conversion ratio, and low component voltage stress. Finally, a 500-W high step-up converter was experimentally tested to verify the feasibility and practicability of the proposed architecture. The results revealed that the highest efficiency of the circuit is 98%.
