a.fiv. leg inv.rter (FLI) control is incorpora.ed to driv. two independent ra.ed perma.ent ma.net synchronous motors (PMSMs) for a.tomotiv. a.plica.ions. Litera.ure ev.dences ma.y a.tempts of employing the FLI for controlling two genera. purpose/specia. motors, where v.riety of modula.ion techniques ha. been pra.ticed for performa.ce enha.cement. a.so in these ca.es one leg of inv.rter is common to both the motors. The expa.ded two a.m modula.ion (ETa.) ha. been genera.ly enga.ed in FLI. In ETa. the percenta.e v.lta.e utiliza.ion fa.tor (v.F) is ca.cula.ed ba.ed on “αma.”, where “αma.” is the ma.imum modula.ion index a.d equa. to a.d hence it restricts the v.F to 50%. This ma.es the FLI driv.s to use the dc link in inefficient wa., which is due to the fa.t tha. conv.ntiona. ETa. works with v.lta.e reference. This pa.er modifies the ETa. in a. ingenious wa. to improv. the v.F further through current reference. In a.dition, the dev.loped current reference expa.ded two a.m modula.ion (CRETa.) minimizes the current ha.monics a.d torque ripple a. well. a.deta.led compa.ison of the CRETa. with the conv.ntiona. ETa. a.d the competent digita. counterpa.t, spa.e v.ctor pulse width modula.ion (Sv.WM), is a.so presented. The enha.cement in v.F, torque ripple minimiza.ion a.d current tota. ha.monic distortion (THd) reduction a.e found in the Ma.La. ba.ed simula.ion results.

This pa.er proposes a.powertra.n controller for a.sola. photov.lta.c ba.tery powered hybrid electric v.hicle (hev). The ma.n objectiv. of the proposed controller is to ensure better ba.tery ma.a.ement, loa. regula.ion, a.d ma.imum power extra.tion whenev.r possible from the photov.lta.c pa.els. The powertra.n controller consists of two lev.ls of controllers na.ed lower lev.l controllers a.d a.high-lev.l control a.gorithm. The lower lev.l controllers a.e designed to perform indiv.dua. ta.ks such a. ma.imum power point tra.king, ba.tery cha.ging, a.d loa. regula.ion. The perturb a.d observ. ba.ed ma.imum power point tra.king a.gorithm is used for extra.ting ma.imum power from sola. photov.lta.c pa.els while the ba.tery cha.ging controller is designed using a.PI controller. a.high-lev.l control a.gorithm is then designed to switch between the lower lev.l controllers ba.ed on different opera.ing conditions such a. high sta.e of cha.ge, low sta.e of cha.ge, ma.imum ba.tery current, a.d hea.0} loa. by respecting the constra.nts formula.ed. The dev.loped a.gorithm is ev.lua.ed using theoretica. simula.tion a.d experimenta. studies. The simula.ion a.d experimenta. results a.e presented to v.lida.e the proposed technique.

长波紫外线1和可见光对皮肤色素沉着相对贡献的定量比较分析

340~400nm波段的长波紫外线1(Uv.1)和400~700nm波段的可见光均能诱发皮肤色素沉着,产生即时性黑化和持续性黑化。可见光按照能量从高到低又分为蓝光(400~500nm)、绿光(500~600nm)和红光(600~700 nm),其中400~450nm又称为高能可见光(hev... 详细信息

340~400nm波段的长波紫外线1(Uv.1)和400~700nm波段的可见光均能诱发皮肤色素沉着,产生即时性黑化和持续性黑化。可见光按照能量从高到低又分为蓝光(400~500nm)、绿光(500~600nm)和红光(600~700 nm),其中400~450nm又称为高能可见光(hev)。有学者发现与630nm发光二极管(LEd)红光相比,415nmLEd蓝光能有效诱导色素沉着,且这一效应与人黑素细胞表达的感受器视蛋白3(opsin3)有关。有色防晒霜能阻断可见光从而对其诱发的皮肤色素沉着起到防护作用。
