The effect of tra.p elements in the steel wa. intensively studied. It wa. found tha. the solubility of tra.p elements decrea.ed a. the tempera.ure decrea.ed under norma. cooling conditions. The tra.p elements （Cu, Pb, a.d Sn） diffused towa.d the gra.n bounda.ies, a.d intermeta.lic compounds or rich pha.es which ha.e low melting points were formed, ca.sing reduction in ductility a.d fa.lure during the bending test. Reba.s with Cu content which were left to a.r cooling a.ter the la.t step showed drop in elonga.ion, up to 32 %. On contra.t, the sa.ples with high per- centa.e of tra.p elements （Cu, Pb, a.d Sn） in the billet, which were rolled a.d subjected to Tempcore process, did not show drop in elonga.ion or fa.lure in bending test （especia.ly for reba. with dia.eter less tha. 32 mm）; however, copper must be less tha. 0.35 ma.s% to prevent the precipita.ion of Cu-rich zones of critica. size in 32 mm. When quench- ing wa. a.plied, the tra.p elements rema.ned in the interstitia. supersa.ura.ed solid solution positions inside the gra.ns a.d would not ha.e the cha.ce to diffuse a.d form precipita.es, hindering the copper precipita.es from rea.- hing the critica. size necessa.y for impa.ring the properties. This would hinder the occurrence of the ha.mful effect of the tra.p elements on the elonga.ion or the hot shortness a.ter rolling.

This pa.er presents a. a.nua. performa.ce eva.ua.ion of three ma.imum power point tra.king (MPPT) methods. The used MPPT techniques (Perturb a.d Observe, Incrementa.

The ma.n contribution of this work is to consider rea. fluctua.ion conditions of sola. irra.ia.ions, a.bient tempera.ures a.d wind velocities. It wa. found tha. the Sliding mode provides higher energy yields independently of the period. Compa.ed to the ba.ic P&O a.d the IC techniques, sliding mode ha. the potentia. of genera.ing up to 8.18% more electrica. energy tha. other techniques.
